Collagen is an essential protein that plays a vital role in maintaining healthy joints, skin, and overall well-being. While humans commonly supplement with collagen, many pet owners wonder if it can benefit their dogs as well. As dogs age, their natural collagen production declines, which can lead to joint stiffness, reduced mobility, and skin issues. The short answer is yes - collagen can be a beneficial addition to your dog’s diet. However, there are important considerations to keep in mind before introducing it.

What Is Collagen and Why Is It Important?

Collagen is the most abundant protein in the body, forming the structural framework of connective tissues, including skin, tendons, ligaments, and cartilage. It provides elasticity and strength, helping maintain overall physical health. In dogs, collagen contributes to joint flexibility, skin hydration, digestive health, and even the integrity of nails and teeth.

As dogs age, their collagen levels decline, resulting in common aging issues such as stiff joints, dull coats, and brittle nails. Environmental factors such as diet, activity level, and exposure to toxins can further reduce collagen production, making supplementation a viable solution for many pet owners.

Benefits of Collagen for Dogs

Collagen provides several health benefits for dogs, much like it does for humans:

Joint Health and Mobility: Collagen is a key component of cartilage, the tissue that cushions joints. Older dogs or those with arthritis may benefit from collagen supplements, as they help maintain cartilage strength and reduce inflammation, improving mobility. Active dogs or working breeds may also benefit from collagen to support joint health and prevent premature wear and tear.

Skin and Coat Health: Collagen plays a major role in maintaining skin elasticity and hydration. If your dog has dry, flaky skin or a dull coat, collagen may help restore moisture and shine, and it can support healing in dogs with skin conditions. Regular collagen intake can also reduce shedding and improve overall coat texture.

Digestive Support: Collagen contains amino acids that strengthen the gut lining. This can be beneficial for dogs with digestive issues such as leaky gut syndrome or food sensitivities by improving nutrient absorption and reducing inflammation. A strong gut lining helps protect against harmful bacteria and supports a balanced digestive system.

Nail and Dental Health: Collagen also supports stronger nails and teeth, both of which are crucial for a dog’s overall health and well-being. Brittle nails can lead to painful cracks, and collagen helps maintain their strength and resilience.

Weight Management and Muscle Health: Since collagen is a protein, it supports lean muscle mass and overall metabolism. Dogs recovering from injuries or those with muscle loss due to aging may benefit from collagen supplementation as part of a balanced diet.

How to Give Collagen to Your Dog

There are several ways to add collagen to your dog’s diet:

Collagen Supplements: Many pet stores sell collagen in powder, chew, or capsule form, specially formulated for dogs. These are convenient and easy to mix into food or offer as treats.

Bone Broth: A natural source of collagen, bone broth is easy to make at home or buy pre-made. It also enhances the taste of meals, making it an appealing addition to your dog’s diet.

Collagen-Rich Foods: Certain foods, such as chicken feet, beef trachea, and fish skin, naturally contain collagen. Including these in your dog’s diet can provide additional health benefits and variety.

Collagen Dosage for Dogs

The appropriate collagen dosage depends on your dog’s weight, age, and the type of supplement used. Most commercial products provide specific guidelines, but general recommendations are:

Small dogs (under 25 lbs): 1 to 2 grams per day

Medium dogs (25 to 50 lbs): 2 to 4 grams per day

Large dogs (50+ lbs): 4 to 6 grams per day

If using natural sources such as bone broth, start with a small amount added to meals a few times per week and adjust as needed. It’s important to introduce collagen gradually to avoid digestive upset, particularly in sensitive dogs.

Potential Side Effects and Considerations

Collagen is generally safe for dogs when given in appropriate amounts. However, some dogs may experience mild digestive upset when first introduced to collagen supplements. If your dog shows signs of diarrhea, bloating, or gas, reduce the dosage and reintroduce it slowly.

Additionally, while collagen supplements can be beneficial, they should not replace a balanced diet. Ensuring that your dog receives adequate protein, healthy fats, and other essential nutrients is crucial for long-term health.

Choosing the Right Collagen Supplement

When selecting a collagen supplement for your dog, consider the following factors:

Quality: Look for high-quality, hydrolyzed collagen peptides, which are more easily absorbed by the body.
Ingredients: Avoid products with artificial additives, fillers, or excessive preservatives. Natural, clean ingredients are always best.
Source: Opt for collagen derived from grass-fed, pasture-raised animals to ensure a higher nutrient profile and purity.
Formulation: Some supplements include additional ingredients such as glucosamine or chondroitin, which further support joint health.

Final Considerations

Collagen is a beneficial supplement for dogs, supporting joint health, skin hydration, digestion, and overall well-being. While generally safe, it’s always best to introduce it gradually and monitor your pet for any adverse reactions. If your dog suffers from joint pain, skin issues, or digestive problems, collagen may be a worthwhile addition to their diet.

As with any new dietary supplement, consulting your veterinarian before starting collagen supplementation is recommended to ensure it suits your dog’s specific needs. By incorporating collagen responsibly, you can help your furry friend maintain a healthier and more active lifestyle well into their senior years.

Should I Be Worried About My Dog Eating Dirt?

Have you ever been out enjoying a peaceful walk or watching your pup play in the backyard, only to witness them suddenly nose-dive into the soil and… start eating it? That immediate feeling of disgust (who eats dirt, eww) is usually followed by a wave of concern. Ultimately, you’re left wondering why your dog would engage in such a seemingly unappetizing habit.You’re not alone! It’s a question that has likely crossed the minds of countless dedicated dog parents. Why? Because this “dirty” habit (see what I did there) is more common than you think!In this post, I will shed light on why dogs eat dirt, the potential risks associated with this habit, help you understand when it’s an unpleasant quirk versus a cause for concern, and most importantly, offer some tips and tricks to help keep your pup safe. Because when it comes to our dogs, peace of mind is priceless!Understanding Your Dog’s Motivation for Eating DirtWhen we see our dogs consuming dirt, it’s natural to immediately wonder why. This seemingly strange behavior, eating non-food items, actually has a scientific name: pica. While occasional dirt-licking might be harmless, chronic pica, where a dog regularly or obsessively eats dirt, can be a sign of underlying physical or behavioral issues that must be addressed. It’s not just about a dirty mouth; it could be a red flag that there’s something bigger at play.Nutritional DeficienciesFor a long time, the most common explanation for dogs eating dirt was a perceived nutritional deficiency. More specifically, many people believed it was a lack of essential minerals like iron. The idea was that dogs instinctively seek out what their bodies are missing. Therefore, if they are missing iron, they will look to eat something that will supply the missing mineral.While this can be a factor, it’s generally less common for dogs fed a high-quality, complete, and balanced commercial dog food. These foods are meticulously formulated to provide all the necessary vitamins, minerals, and nutrients a dog needs. So, while it’s a possibility, it’s often not the primary culprit.Behavior Roots of Dirt EatingMore often than not, the reasons behind eating dirt are behavioral. Just like humans, dogs can exhibit a range of behaviors that may seem “off” or out of character due to their emotional and mental states.Boredom and lack of stimulation: Dogs are highly intelligent creatures who need physical and mental enrichment. If your dog isn’t getting enough walks, playtime, or interactive toys, they may eat dirt to entertain themselves. It’s a novel texture, a different smell, and an activity to occupy their time.Anxiety and stress: Just like some people chew their nails when they are feeling nervous, some dogs develop coping mechanisms for stress and anxiety. Eating dirt can be a repetitive, self-soothing behavior for dogs experiencing separation anxiety, fear of loud noises, or other environmental stressors.Curiosity and exploration: This is especially true for young puppies. The world is a brand-new place, and puppies explore everything with their mouths. Dirt offers fascinating smells, textures, and tastes that they may be investigating out of pure curiosity, similar to how human toddlers put everything in their mouths.Attention-seeking behavior: Let’s be honest; seeing your dog eat dirt usually triggers a strong reaction from you. Perhaps you gasp loudly, quickly dash to stop them, or call out a firm “no!” If a dog learns that eating dirt gets them immediate attention, even if it’s negative attention, they might repeat the behavior just to get you to engage with them.Instinctual behavior: While highly domesticated, dogs still possess some primal instincts passed down from their wild ancestors. Wild dogs might ingest small amounts of dirt or soil to aid digestion, firm up loose stools, or perhaps even obtain trace minerals. However, this instinct is far less relevant for most modern house dogs and generally a thing of the past.Tummy TroublesSometimes eating dirt is a sign of underlying gastrointestinal problems. Just like dogs sometimes eat grass when they have an upset stomach or feel nauseous, they might also ingest dirt. They could be attempting to soothe an irritated digestive tract, induce vomiting to relieve discomfort, or simply looking for something to help them feel better. If your dog suddenly starts eating dirt and seems to be experiencing stomach issues, it’s a strong sign that their digestive system might be trying to tell you something.Tasty TemptationsOf course, there is always the possibility that something enticing is tempting them to dive in for a taste. Take a moment to consider the area from which your dog is snagging the dirt. Is there a reason they may believe the dirt could be delicious? For example, if you recently fertilized the garden, the scent of manure could be drawing your pup in.The Risks: When Dirt Eating Can Be DangerousWhile a casual lick of dirt might seem harmless, this habit could easily cross the line into much more concerning territory. Consistent or extensive dirt eating carries a long list of potential dangers for your pup.Gastrointestinal Blockages and ObstructionsOne of the most immediate and serious concerns when a dog eats dirt is the risk of a blockage or obstruction in their gastrointestinal tract. It’s not just the dirt itself; it’s often what’s mixed in with the dirt that leads to trouble. Small stones, pebbles, sticks, plastic pieces, or other debris can easily be ingested along with the soil. These non-digestible items can accumulate in the stomach or intestines, leading to a partial or complete blockage.This is a veterinary emergency that often requires surgical intervention. If not addressed, it can quickly turn life-threatening. Watch out for symptoms such as:Persistent vomitingLethargy and weaknessLoss of appetiteAbdominal pain or tendernessStraining to defecate or inability to pass waste

Should I Give My Dog Supplements?

Are you wondering if you should give your dog supplements, in addition to his diet? Your dog food dollars can go a lot further if you do! In a recent study by InClover Research (independent pet supplement company out of Boulder, CO), they found in analyzing Google Trend data that “pet supplement” searches are at an all-time high! That’s almost 300 times higher than ever before. So, what does this mean as a pet parent? Is it time to give your dog vitamins? Aren’t dogs getting enough nutrition from the food they eat? We asked InClover’s Founder and President, Rebecca Rose the same question. “I used to believe your pet’s food was a baseline indicator of their health — I don’t believe that anymore.” Rebecca is a biochemist gone rogue, so to speak. She’s dedicated her life to researching optimal nutrition and health and her passion for pets carried her into founding and owning InClover Research. It’s a pet supplement company based in Boulder, CO, that prides itself on blending the wholistic and allopathic properties of nutrition to optimize your pet’s health. Breaking down the PROS of PREbiotics The market is flooded with pet supplements, including infamous CBD cure-alls. There is no single supplement that is guaranteed to fix all ailments, especially in pets. But for pet owners looking to promote hip and joint function, optimize their pet’s digestion, strengthen their immunity, and thrive in their best health, there are a few places we’d start. What’s the difference between prebiotics and probiotics (which should I use)? Prebiotics selectively feed only the good bacteria in your pet’s gut — this allows native bacteria to flourish while starving the bad bacteria. Probiotics are usually from dairy strains and soil — most will die at fluctuating temperatures and low pH so aren’t as potent in promoting optimal digestion. Do prebiotics help pet digestion? The answer is YES! A 2020 report from Lumina found prebiotics are a personalized approach to growing the beneficial native bacteria in the digestive tract. Prebiotics were also the 2020 marketplace winner for human supplement revenue growth with CBD products showing the biggest decline. Did you know, 70 percent of your pet’s immune system is housed in their digestive tract? Apart from prebiotics being a powerhouse for nutrition, prebiotics are also great for digestive health, immune support and weight control in dogs and cats. Giving your dog/cat a daily prebiotic like those made by InClover, including Optagest, can have profound impact their overall health. How does it work? Optagest is the ONLY clinically tested digestive aid with USDA organic inulin. Inulin works with digestive enzymes to help break down food in your pet’s GI tract, allowing for better nutrient absorption. This helps you get the most bang for your buck when it comes to feeding your dog- hey, you invest in quality dog food, might as well make the most of it, right? How do you know digestive supplements like Optagest are working? Like we said, Rebecca dedicated her life to pet health and as a biochemist, didn’t stop working until she knew her product worked. Optagest works fast — typically within 1-3 days depending on your pet’s unique body type. What can you expect when you start your dog/cat on prebiotics? Normal stools, and normal odorLess digestive upsets (vomiting)Balanced digestion (less gas and bloating- especially common in bully breeds)Sweetened breath Supplements only work if you take them! Creating new habits for ourselves and our pets can be challenging but worth the reward, especially when it comes to seeing our pets live their best lives. If digestion isn’t pulling at you, consider creating health habits for your dog/cat dental health. Along with a full range of supplements InClover manufactures, BioBrilliant is one of their must-haves. BioBrilliant is a great choice for pet parents investing in long term mouth, and dental health. A Bit More About Dental Health Periodontal disease is one of the most common health problems found in pets? The American Veterinary Medical Association estimates that 80 percent of dogs by the age of 2, will have some form of periodontal disease, and 85 percent of cats by the age of 4 will be affected by dental disease. Crazy, right? Again, there is no magic dust you can sprinkle on your dog’s food to give them beautiful teeth overnight, but daily use of BioBrilliant helps dissolve plaque, sweeten their breath, and promote positive gum health helping keep our dogs and cats comfortable during mealtime and any other time, which makes us very happy too. Picking the right supplement shouldn’t be a guessing game, and all InClover’s supplements are sourced with carefully considered ingredients including, the Goat’s Milk Whey that goes into every bottle of BioBrilliant. InClover sources this sweet treat from a farm in Maine (and we can assure you, the goats are EXTREEMLY cute). Apart from providing the highest quality supplements, InClover believes in operating at the highest standards for not only the health of our pets, but for our planet as well.

Why Is My Dog Gaining Weight? Should I Be Concerned?

Have you recently noticed a little more padding than there used to be when petting your pup? Does their collar appear a tad snugger than it was just a few weeks ago? As loving dog parents, we are generally the first to notice when something changes, including changes in our best friend’s weight. But when should you be concerned about those added pounds?While a little extra weight may initially seem unimportant, sudden weight gain in dogs can sometimes be a warning sign of an underlying medical issue. In this post, I’ll help you uncover the possible reasons for your dog’s growing waistline, including when to see a veterinarian. Plus, I’ll offer some actionable tips to help keep your pup at a healthy weight.Recognizing Sudden Weight Gain in Your DogIt can sometimes be tricky to spot changes in your dog’s weight based on looks alone, especially if they have a lot of fur. That’s why it’s important to take time regularly to do a quick check on your dog’s body condition. Here are some practical ways to do this:The Scale: If your dog isn’t too large, the obvious answer is to use a scale. Regularly weighing your dog at home will give you concrete numbers to check. Most veterinarians will also allow their clients to come in and use their scale between checkups.The Feel Test: If your dog is a healthy weight, you should be able to easily feel their ribs when running your hands along their body without pressing too hard. If you’re looking down at their body from above, you should be able to see a visible waist tuck.The Look Test (with Caution): Look at their overall body shape. Are they looking rounder, especially around the belly? Do they appear to be losing definition?Keep in mind that relying on how they look may be misleading, causing you to miss signs of trouble. Long-haired breeds can hide extra weight under their fur. Seasonal changes in your dog’s coat thickness may also give the illusion that they have gained weight when they haven’t. Your best approach is not to rely on visual appearance alone.Not worried about your dog’s weight right now? This is the perfect time to weigh them and get a solid baseline. By knowing their healthy weight, you’ll have something to compare it to if you are concerned that there may be a worrisome change in the future.Potential Reasons Your Dog is Gaining WeightWhen our dogs start to pack on the pounds unexpectedly, it’s natural to wonder what’s happening. Especially because some potential explanations serve as a warning sign of something far more serious.Often, the answer lies in a simple imbalance between the calories they consume and the energy they expend each day. However, other factors, including changes in their activity levels and even underlying health conditions, can also play a role.Let’s look at some of the most common reasons for sudden weight gain in dogs.Dietary ChangesArguably, the most common reason for a dog’s growing waistline is an increase in the number of calories they eat with no matching change to their activity level (or a decrease in activity with no change to their meals). This can manifest in several ways, such as:A recent switch to a food with a higher calorie density, even if the portion size remains the sameAn increase in the frequency or size of treatsThe addition of table scraps and other human foods to their dietMiscommunication between family members about whether/how much your dog has eatenIt’s crucial to remember the importance of correctly measuring your dog’s food portions to avoid unintentional overfeeding. Check the packaging of your dog’s food for the feeding guidelines, as this is unique to each brand and formula.Lower Activity LevelsEven if your dog’s diet hasn’t changed, a reduction in their exercise levels could lead to weight gain. Just like with humans, fewer calories burned means more stored as fat.There are several reasons why a dog’s activity levels may decrease. As dogs get older, they naturally slow down. Injuries or chronic pain, such as canine arthritis, can limit their mobility and ability to be as active as they once were at their prime. They may also be less active due to changes in your lifestyle or daily routine. For example, if your work schedule is suddenly hectic, it may lead to fewer or shorter walks.Finally, consider the environmental factors that could impact their willingness or ability to stay active. For example, extreme weather conditions like sweltering summer heat or chilly winter temperatures may result in less outdoor playtime.Underlying Medical ConditionsWhile the delicate balance between diet and exercise is often the primary culprit, sudden weight gain can sometimes be a warning sign of an underlying medical condition. Several conditions can lead to weight gain, and as responsible dog parents, we must be aware of these possibilities: Hypothyroidism: A condition where the thyroid gland doesn’t produce enough thyroid hormone, often slowing a dog’s metabolism, leading to weight gain even with a normal diet Cushing’s Disease (Hyperadrenocorticism): An overproduction of cortisol, which can increase appetite, alter fat distribution (often leading to a pot-bellied appearance), and cause weight gain Heart Disease: This sometimes leads to fluid retention, which may manifest as a bloated abdomen or the appearance of rapidly gaining weightOrgan Enlargement: When key organs in the abdominal area, such as the liver or spleen, become enlarged, they can contribute to abdominal bloating or swelling and a feeling of weight gainMedications: Certain medications, particularly corticosteroids, are known to increase appetite, leading to weight gain as a side effectFluid Retention (Edema or Ascites): The buildup of fluid in the body’s tissues or abdomen can be caused by various underlying conditions (like the aforementioned heart disease) and result in a rapid increase in apparent weight

At What Age Should I Start Socializing My Dog?

Socialization is one of the most critical aspects of raising a well-adjusted and confident dog. Proper socialization helps prevent fear, anxiety, and aggression while fostering positive interactions with people, other animals, and new environments. But when is the right time to start? The short answer: as early as possible. However, different stages of a dog’s life require different approaches. Here’s what you need to know.The Critical Socialization Period: 3 to 16 WeeksPuppyhood is the optimal time for socialization. Puppies go through a crucial developmental window between 3 and 16 weeks of age, during which they are most receptive to new experiences. Exposing them to various sights, sounds, and situations during this period helps them grow into well-mannered adult dogs.When to BeginThe American Veterinary Society of Animal Behavior (AVSAB) recommends starting socialization as early as 7 to 8 weeks old, even before full vaccination. However, exposure must be done in safe, controlled environments to minimize health risks. Structured puppy classes, playdates with fully vaccinated dogs, and supervised outings can be excellent ways to introduce new experiences safely.Effective Socialization StrategiesSuccessful socialization involves controlled, positive exposure to a wide variety of experiences. Here’s how you can help your puppy develop confidence:Introduce New People: Expose your puppy to people of different ages, appearances, and voices. This helps prevent fear of strangers later in life.Expose to Different Environments: Take your puppy to pet-friendly locations, parks, and sidewalks. Introduce them to common sounds such as traffic, doorbells, and household appliances.Use Positive Reinforcement: Reward calm and friendly behavior with treats and praise. This creates positive associations with new experiences.Organize Puppy Playdates: Arrange supervised play sessions with vaccinated puppies or well-behaved adult dogs to encourage good social behavior.Introduce Different Surfaces and Objects: Let your puppy walk on different textures like grass, pavement, sand, and carpet. Exposure to unusual objects such as umbrellas, bicycles, and strollers can help prevent fear reactions in the future.Acclimate to Handling: Regularly touch your puppy’s paws, ears, and mouth to prepare them for grooming and veterinary visits. Reward them for remaining calm during handling exercises.

What Should I Do if My Dog Won't Stop Coughing?

Imagine waking up in the middle of the night to the sound of your dog’s persistent coughing. It’s a scenario that no pet parent wants to face, one that can bring panic and stress. But it’s also an important reminder about one crucial point: Coughing in dogs, while sometimes seemingly minor, can be a sign of underlying health issues – some of which can be pretty serious!The causes of a dog’s cough can vary from simple irritations to more concerning medical conditions. That’s why it’s so important to recognize that a persistent cough isn’t something to ignore.This blog post will provide the information you need to better understand your dog’s cough, identify the potential causes, and (most importantly) know when to seek immediate veterinary help. I will share the different types of coughs, how to recognize the more common causes, and steps you can take to prevent that unwanted cough; keeping your dog happy and healthy.Understanding Coughing in DogsCoughing is a natural reflex designed to clear the airways of irritants. An occasional cough might not be a cause for alarm. In fact, it may even be healthy. For example, if your dog was sniffing outdoors and inhaled a bunch of pollen, coughing could effectively clear this common allergen out of their system. But a persistent cough is a different story.Your dog’s ongoing or constant coughing could signal that something isn’t right, and paying attention is crucial. Understanding the nuances of your dog’s cough and communicating them to your veterinarian can help you reach a diagnosis and find a suitable treatment option faster.Here are the most common types of canine coughs:Honking Cough: Often described as sounding like a goose, this type of cough is frequently associated with kennel cough or tracheal collapse.Dry, Hacking Cough: This type of cough might point towards kennel cough as well, but it could also be triggered by many common allergies or other irritants your dog has been exposed to. Wet, Productive Cough: A wet cough often sounds like your dog is bringing something up. This can be more concerning and is usually associated with pneumonia, heart disease, or other severe medical conditions.Coughing Followed by Vomiting or Gagging: While sometimes seen with kennel cough, it could signal something more serious if your dog is vomiting after they cough.The distinction between these different types is so important. By carefully noting the specific sound and characteristics of your dog’s cough, you can provide your veterinarian with key information they may not be able to collect during an appointment. We’ve all been to a vet appointment where we’ve tried to explain what’s happening because it somehow magically stopped the moment we walked through the door.A short video recording on your phone can be incredibly helpful, allowing your vet to hear the cough firsthand.Common Causes of Coughing in DogsSeveral factors can contribute to your dog’s cough, ranging from minor ailments to serious medical conditions. As a responsible and loving dog parent, I recommend learning the most common causes and what other symptoms to look out for to help you better understand what your dog is experiencing.Kennel Cough (Infectious Tracheobronchitis)This highly contagious respiratory infection often spreads in places where large numbers of dogs congregate, such as boarding facilities, dog parks, and kennels. It’s characterized by a distinctive “honking” cough, which may be accompanied by other cold-like symptoms. While kennel cough will often clear up on its own (much like a human cold), sometimes antibiotics or cough suppressants are necessary. Fortunately, vaccination is an effective preventative measure, especially if you know your dog often frequents high-risk areas.Tracheal CollapseThis occurs when the trachea, or windpipe, weakens. Tracheal collapse most often affects small breeds, but it can happen in any size of dog. The hallmark symptom is a goose-like “honking” couch, which can worsen with excitement or exercise. If you suspect you may be dealing with tracheal collapse, contact your veterinarian. Treatment options include medications, weight management, and, in some cases, surgery.Heart DiseaseThe heart is likely not the first thing that comes to mind when considering the cause of a cough, but coughing can be a significant symptom of heart disease, particularly heart failure. This couch is often worse at night or after exercise and may be accompanied by other signs of heart trouble, like fatigue, weakness, and difficulty breathing. If your dog is diagnosed with heart disease, they will need ongoing management of the underlying heart condition by your veterinarian.Pneumonia Pneumonia, an inflammation of the lungs, can be caused by bacterial, viral, or fungal infections. It is typically associated with a wet, productive cough. Other common symptoms of pneumonia in dogs include:FeverDifficulty breathing or swallowingNasal dischargeRapid heart rateAltered moodChanges in appetiteLethargy or sluggishnessTreatment for pneumonia usually involves antibiotics. Your dog may also require supportive care, addressing some of the symptoms to allow their body to heal. For example, if your dog is struggling with loss of appetite, your vet may recommend an appetite stimulant.Allergies and IrritantsJust like humans, dogs can suffer from environmental allergies and react to inhaled irritants like smoke, dust, and pollen. These allergies and irritants usually trigger a dry, hacking cough. You may also notice other signs your dog is suffering from allergies, such as sneezing, a runny nose, itchy eyes, ear infections, inflamed skin, and paw licking. Treatment usually involves antibiotics and supportive care.Canine DistemperThis serious and potentially fatal viral illness is thankfully preventable through vaccination. However, if you have a young puppy who hasn’t completed their puppy vaccination schedule, they are at risk. Coughing is one of the most common symptoms, along with fever and neurological signs. If you suspect your dog may have distemper, it is an emergency and requires immediate veterinary care. Treatment is supportive and often intensive.

Is It Safe to Keep Fish in a Small Bowl?

Fish can be peaceful, mesmerizing pets, perfect for those looking to add a bit of calm to their daily routine. But when it comes to setting up the right environment for them, the classic image of a lone goldfish in a clear, round bowl raises an important question: is it actually safe to keep fish in a small bowl?The short answer? No - not really.While fish bowls are often marketed as a simple, low-maintenance solution (especially for beginners), they fall short in several critical ways when it comes to keeping fish healthy and happy. Let’s explore why.Why Small Bowls Are Problematic for Fish1. Poor Water QualityOne of the biggest challenges in fishkeeping - especially in small containers - is maintaining clean, safe water. In a bowl, fish waste builds up quickly, causing harmful levels of ammonia and nitrates. Without a filtration system to remove these toxins, the water becomes increasingly dangerous for the fish. Even frequent water changes often aren’t enough to keep up in such a small volume.

How to Choose the Right Pet for Your Lifestyle

Bringing a pet into your life is exciting, but it's also a big decision. Pets aren't just cute companions; they depend on us for their health, happiness, and daily care. That’s why it’s so important to make sure the pet you choose actually fits your lifestyle, your home, and your long-term plans.Choosing thoughtfully can mean the difference between a joyful experience and a stressful one, for both you and your future pet. Here's what to think about before you say yes to a new furry (or scaly, or feathered) friend.Start by Looking at Your LifestyleBefore you even start thinking about breeds or species, ask yourself: what does a typical day look like for you?If you’re someone who loves being outside, running, hiking, or going on long walks, an active dog like a retriever or a border collie might be the perfect adventure buddy.But if your schedule is packed, you travel a lot, or you just love cozy nights at home, a lower-maintenance pet — like a cat, a hamster, or a fish - might be a better match.Be honest about how much time and energy you can consistently offer, not just on your best days, but every day.Think About Your HomeNext up: where do you live?Your living space plays a huge role in what kind of pet will thrive with you.If you’re in an apartment, a giant dog who needs room to run might not be the best fit.Smaller pets like birds, reptiles, or small mammals can often do great in smaller spaces, as long as their setups are thoughtfully designed.

Chubby Rescue Cat Arrives at Shelter ‘Too Large’ for the Scale

As a volunteer in the rescue space, you see many things – the heartwarming reunions, the shy pets slowly coming out of their shells, and sometimes, the cases that really make you pause. When Big Bertha arrived at Jefferson County Humane Society in late February, she was definitely one of those cases. Even for a seasoned volunteer who has seen animals in various states of health, the sheer size of this sweet girl was startling! This wasn’t just a chunky feline; Bertha, with her petite frame and short legs, weighed in at a shocking 21 pounds – so large, in fact, that the standard cat scale at the shelter couldn’t even register her weight. They had to resort to the dog scale to get an initial reading. Upon arrival, it was clear that Bertha was facing many health issues directly linked to her size. The shelter’s vet team immediately got to work on creating a carefully managed weight loss plan that included specialized wound care and a gentle exercise regimen. In the early days of her workouts, she would be aided by a sling to support her movement, allowing her to burn calories without putting too much strain on her petite frame. The road to recovery was expected to be long, but the entire shelter team fell in love with Bertha, committing to do the work necessary to help her regain her health and quality of life. Bertha’s previous owner made the difficult decision to surrender her to the shelter, recognizing their inability to provide the necessary care, especially the extensive veterinary attention she clearly needed. “Her mouth was full of infected, loose, broken teeth,” explained Brandi DeNoon-Damewood, the development manager at the shelter. “Most kitties with teeth this bad are very thin from lack of appetite and pain with chewing. However, Bertha only ate soft/canned food that she could easily slurp down, and as her pain increased, she ate more and more – just like humans, kitties can become addicted to the happy feeling we get with a full belly. It is believed that she was a street kitty prior to her owner, which also helps shed a little light onto her food guarding and overeating. She may have gone days without any food whatsoever, and those days are forever carried with her throughout the rest of her life.” A significant step in Bertha’s journey was dental surgery shortly after her arrival. This addressed her painful mouth, not only for her comfort but also paved the way for a healthier relationship with food. Initially, Bertha struggled with breathing and mobility due to her weight, and she was understandably quiet and fearful. However, as the pounds began to come off, a beautiful transformation occurred. “She LOVES to ‘talk,’ and when she wants attention, she will call out for you to come over to her,” DeNoon-Damewood shared, noting that this vocalization was likely a learned behavior that she developed due to her limited mobility. “Her purrrrsonality has blossomed into a vibrant, social, loving kitty.” By the end of March, Bertha had reached a significant milestone, weighing in at 16 pounds. While she still had more weight to lose, this progress meant she was ready to take the next step in her journey – finding a forever home. At the beginning of April, she was adopted by a loving individual committed to continuing her weight loss journey and providing her with a lifetime of love and care. Bertha’s story is a powerful reminder of the complex factors that can lead to a pet being surrendered and the importance of shelters and rescue organizations for those in need.
