Published:  August 28th, 2026

Watching your dog grow older isn’t always easy. 


They may slow down a little, sleep more, or take longer to get up from their favorite spot on the couch. 


While some changes are a normal part of aging, others can be signs that your dog needs a little extra care.


So, what should you keep an eye on as your four-legged friend gets older? Here are five common things to watch for.

1. Changes in Mobility

Is your dog suddenly struggling to climb the stairs, jump into the car, or get comfortable after a nap? Changes in mobility can happen as dogs age, often because of stiff or painful joints.


You might notice that your dog is less enthusiastic about walks or takes longer to get moving in the morning. 


Don't assume they simply don't want to exercise anymore. Your vet can help determine whether pain, arthritis, or another issue is behind the change.


At home, rugs on slippery floors, ramps, and a supportive bed can also make getting around easier.

👉 Give your older pup a cozy place to rest with the Bedsure Orthopedic Dog Bed, featuring supportive cushioning and a removable, washable cover.

2. Changes in Weight

An older dog's weight can sometimes creep up as they become less active.


However, unexplained weight loss shouldn't be ignored either.


Changes in appetite, muscle mass, or body condition can sometimes point to an underlying health problem. 


Keep an eye on how much your dog is eating and check their weight regularly. If you notice a significant or unexplained change, speak with your vet.

3. Dental Problems

Bad breath isn't necessarily something you just have to accept because your dog is getting older.


Dental disease is common in dogs and can become more problematic with age.


Look out for red or swollen gums, difficulty chewing, excessive drooling, loose teeth, or a sudden reluctance to eat hard food. 


Regular dental care can help keep your dog's mouth healthier.

4. Changes in Behavior

Has your normally confident dog suddenly become anxious, confused, clingy, or withdrawn? 


Behavioral changes can have a number of causes, including pain, hearing or vision loss, and age-related cognitive changes.


You may notice your dog pacing at night, getting confused in familiar places, or seeming unsettled for no obvious reason.


Keeping their daily routine predictable can help, but any significant or persistent change is worth discussing with your vet.

5. Lumps, Bumps, and Other Physical Changes

As you groom or cuddle your older dog, get into the habit of checking for anything new or unusual.


This could include lumps, bumps, changes to their skin, sores that aren't healing, or changes in their eyes.


Not every lump is dangerous, but it's difficult to tell what something is just by looking at it.


If you discover a new growth or notice a change in an existing one, have your vet check it out.

Final Thoughts

Aging is a normal part of life, but keeping an eye on changes can help you spot problems early. 


With regular vet care and a little extra attention at home, you can help your older dog stay comfortable and happy.

Summer Travel Planned? Prep for a Hotel Stay with the Family Dog

(photo credit: New Africa / shutterstock.com)Our pets are family, and just like with kids, we wouldn’t dream of excluding them when vacation time rolls around. And whether we’re off on a weekend getaway or a longer, cross-country journey, hotels can often factor into these travel plans.Yet unlike when we bundle up the pooch and take them RVing or to a friend’s cottage, a hotel brings a wealth of other concerns. To keep things comfortable for your pet, hotel management, other guests, and also for your own peace of mind, a little pre-prep goes a long way.Thinking Ahead Keeps Things SeamlessPicking the Right HotelPet-friendly hotels and motels are no longer a novelty. Recognizing the rapidly rising number of travellers who want to bring the fur kid along, the hospitality industry was quick to – quite literally – take steps to accommodate this burgeoning market.But zeroing in on the best pet-friendly hotel for your extended family requires a little research. For example, if your dog needs long or frequent walks, look for one that is located close to walking trails, parks, or leash-free options. There will be an added fee for bringing your pet, and it will vary from hotel to hotel. Similarly, weight restrictions will be in play, as well as the number of pooches you’re permitted to bring in. If travelling on a budget, you may want to shop for the lowest rates and for properties that have a flat fee versus per-pet fee.When You ArriveSo, you’ve chosen your hotel and are ready to start packing that suitcase. Know that there will be rooms already designated for pet accommodation to ensure future guests won’t be subjected to potential allergy triggers. But even pre-assigned rooms can include options. So, here are a couple of tips for getting the best possible space for you and your pet.Ask for a main-floor room where you have easy access to the outdoors. This makes potty breaks quick (important in the middle of the night) and avoids the need for elevators or passing through a crowded lobby.If possible, choose a room at the end of a hall. Away from ice machines, elevators, and other noisy, high-traffic areas that can agitate your dog when you’re not around.Once you settle in, plan to spend a couple of hours with your pooch. Walk outdoors, cuddle in the room… take the time to help him become familiar with this new space. Especially if you plan to leave him there on his own at some point during the stay.Room Set UpThe odds are you will be leaving your room from time to time and sometimes, for more than a couple of hours. When our pets need to stay behind, we all want to make sure they’re comfortable and feeling secure in these unfamiliar surroundings. Here’s how you do that:

What Are Cat Zoomies and Why Do They Happen Late at Night

Every cat parent knows the feeling when a quiet evening turns into an impromptu racetrack. One minute, your cat is resting peacefully, and the next, they are launching off the back of the couch and sprinting down the hallway with wide eyes and a puffed tail. This sudden explosion of energy is incredibly common, yet watching your cat transform into a blur of motion without warning can leave you wondering what exactly caused the outburst.Known scientifically as Frenetic Random Activity Periods (FRAPs), or more commonly as “the zoomies,” this behavior is completely natural. By understanding the instincts and triggers behind these sudden sprints, you can learn how to safely channel that extra energy, protect your home, and ensure your cat is living their best life.Disclosure: PetGuide may receive a small affiliate commission from purchases made via links in this article, but at no cost to you.The Science Behind the Blur To truly understand why your cat experiences these bursts of speed, it helps to look at their evolutionary blueprint. Even though today’s domestic cats live comfortable indoor lives with full food bowls and cozy sleeping spots, they still hold on to the biological wiring and predatory instincts of their wild ancestors. When it comes to hunting, cats are solitary ambush predators. In the wild, their survival depends on short, explosive releases of energy to stalk, chase, and capture their prey. Because they don’t hunt in packs or run long distances over hours, their bodies are designed for short, rapid sprints rather than endurance running. With no need to hunt for their food, an indoor cat conserves this energy all day long. Between napping for up to 16 hours and lounging in their favorite spots, a massive build-up of both physical and mental power accumulates. When they can no longer contain that energy, the cat experiences a FRAP. In short, the zoomies are a safe, efficient physical release valve for that stored-up power. When an episode is about to begin, you can often see the physical signs of this energy starting to take over your cat’s body. Their pupils will dilate significantly, allowing them to absorb more light and focus on their surroundings, and their ears may twitch forward or pin back slightly. They will often crouch low, and their tail may quiver briefly just before the launch, signaling that the pressure valve has opened and the sprint is underway. Understanding this helps reframe the behavior entirely. It’s not a sign of a behavioral problem or a lack of discipline, but rather a reflection of a healthy animal responding to excess energy and their biological programming. Common Triggers for the Zoomies While a zoomie episode can happen at any time, you have likely noticed that your cat tends to sprint around the same time each day. These episodes are rarely random. Instead, they are usually sparked by specific shifts or environmental cues that signal it is time to move. The Post-Litter Box Rush One of the most common triggers for this behavior is the post-litter box sprint. Many cats will do their business and immediately launch into a high-speed lap around the house. This is a daily routine in our house for my youngest cat, Theia. There are two primary reasons for this sudden burst of movement: Vagus Nerve Stimulation: Passing waste stimulates the vagus nerve. In cats, this stimulation can cause a brief drop in blood pressure followed by a sudden rush of endorphins, leading to a physical feeling of high energy or mild euphoria. Survival Instinct: In a wild environment, waste leaves a distinct scent trail that could give away their position to larger predators. Sprinting away from their elimination site is an instinctual survival mechanism to put immediate distance between themselves and the spot. The Twilight Hour Cats are crepuscular, which means that they are most active during the twilight hours of dawn and dusk. This is the exact time their wild ancestors would naturally hunt, as prey animals are active and the lower light provided them with natural camouflage. When dusk hits, your indoor cat’s biological clock signals that it’s time to hunt, often resulting in a severe case of the evening zoomies. Environmental Triggers Sometimes, a minor shift in your cat’s environment can trigger an episode. The scent of fresh air from an open window, the sound of a bird outside, a sudden shaft of light moving across the floor, or even a brief, playful interaction with another pet can provide just enough mental stimulation to set off a physical burst of energy. Distinguishing Play from Signs of Trouble  For most cats, a quick sprint around the living room is a sign of a thriving, happy animal who feels secure enough in their environment to let loose. However, it is important to understand when hyperactive behavior crosses the line from a healthy release of energy into a sign of discomfort or stress. Healthy zoomies generally last for a few minutes before the cat settles back into a relaxed state. Your cat’s body language afterward should be calm, with normal breathing resuming quickly. These bursts of energy typically align with the triggers discussed earlier, such as the dawn and dusk hours or a successful trip to the litter box. When the frantic behavior becomes frequent, prolonged, or is accompanied by other unusual warning signs, it warrants a closer look. Signs of Anxiety or Frustration: If your cat is pacing constantly, vocalizing with loud, distressed meows, or sprinting away from a specific spot in a panicked way, the zoomies may actually be a manifestation of chronic boredom, environmental stress, anxiety, or frustration from an unmet need. Feline Hyperesthesia Syndrome (FHS): This neurological condition can cause sudden, painful nerve sensations along the spine. A cat with FHS might suddenly bite at their tail, ripple the skin on their back, and bolt across the room as if they are trying to run away from their own skin. Underlying Health Conditions: Flea infestations, severe skin allergies, or an active thyroid ( hyperthyroidism), which his particularly common as cats age, can all cause sudden, uncharacteristic bursts of energy. If your cat’s zoomies appear to be frantic, painful, or out of character, a thorough exam with your veterinarian is always the best step. They can rule out physical discomfort or medical conditions that may need medical help to resolve.

Ringworm in Pets: 5 Urgent Steps to Stop the Spread Fast

Vetr Offers A Steady Supply Of Albendamax When It’s Needed Most

For many livestock producers, spring is not just another season. It is a tightly managed window where timing, treatment, and access to essential inputs determine how the rest of the year unfolds. This year, that balance has been harder to maintain as albendazole-based treatments become less predictable to source across key markets.In this environment, Vetr is not stepping in as a newcomer. It is reinforcing a position it has been building for some time. The company’s latest announcement around the availability of its albendazole-based treatment, Albendamax, underscores a broader narrative. Vetr has consistently approached the livestock health market with a focus on challenging conventional supply dynamics. Now, as availability gaps become more visible across the industry, that approach is drawing sharper attention.Albendazole has long been a reliable tool for managing internal parasites in livestock, particularly during the spring when treatment timing directly impacts herd performance. This seasonal window is not flexible. Producers depend on access to treatments to maintain herd health, optimize weight gain, and prevent longer-term complications that can affect productivity across the year.When supply becomes uneven, the consequences are immediate.Reports from across the agricultural sector point to ongoing inconsistencies in sourcing albendazole-based products. While not always formally classified as a shortage, the reality for many producers is defined by delayed shipments, limited availability, and the need to adjust purchasing strategies in real time. These disruptions reflect deeper structural challenges within the market, including concentrated manufacturing and a supply chain that remains sensitive to fluctuations in demand.Vetr’s position within this landscape is distinct.Rather than reacting to disruption, the company has built its model around anticipating it. The availability of Albendamax during a period of heightened demand reflects a continuation of that strategy. It signals an emphasis on maintaining consistency where others have struggled to do so, particularly in a category where reliability is closely tied to operational success.This is where Vetr’s disruptive identity becomes more tangible.Disruption in the animal health sector is often framed in terms of innovation or pricing. Vetr’s approach centers on something more fundamental. It challenges the assumption that supply volatility is an unavoidable part of the market. By focusing on continuity and accessibility, the company is redefining what producers can expect from their suppliers.That philosophy is closely tied to the leadership behind the company. Andrew Hamilton, the founder of Vetr, has built a reputation as a biotech innovator focused on solving supply-side inefficiencies across complex treatment markets. Based in Grants Pass, Oregon, Hamilton has been described as a hands-on builder rather than a purely academic figure, with experience spanning formulation strategy, manufacturing coordination, and commercialization in tightly regulated environments. His work has consistently centered on identifying overlooked bottlenecks and building systems that address them directly, rather than working around them.Albendamax serves as a clear example of that philosophy in action.Its presence in the market at this moment is not incidental. It reflects a deliberate alignment with the needs of producers during one of the most time-sensitive periods of the year. Instead of adjusting to the market after disruptions occur, Vetr appears to be positioning itself ahead of those cycles, ensuring that availability is not left to chance.For producers, this shift carries practical significance.Livestock operations are built on planning and precision. Treatment schedules are mapped out well in advance, and the margin for error is limited. When a key input like albendazole becomes uncertain, it introduces risk that extends beyond a single purchase decision. It affects herd health outcomes, financial projections, and overall operational confidence.In that context, consistency becomes a form of disruption in its own right.Vetr’s ability to maintain supply of Albendamax during a period of broader inconsistency highlights a contrast within the market. It demonstrates that reliability is not simply a baseline expectation, but a strategic advantage when executed effectively. This is particularly relevant in a sector where producers have historically had to navigate unpredictability as part of their operating environment.The company’s role, then, is not defined by filling a temporary gap. It is defined by challenging the conditions that allow those gaps to persist.Albendazole supply constraints have surfaced before and are likely to reappear without structural changes. By maintaining a consistent presence, Vetr is positioning itself as a company that does not just respond to these cycles but actively works to mitigate their impact.Albendamax is central to that effort.It represents more than a product offering. It reflects a broader commitment to reshaping expectations around supply reliability in livestock health. At a time when producers are recalibrating how they source essential treatments, that commitment is becoming increasingly relevant.Whether viewed through the lens of market dynamics or day-to-day operations, the message is clear. Vetr is not emerging in response to disruption. It is using this moment to demonstrate the strength of a strategy it has been executing all along.And for an industry where timing is critical and certainty is rare, that distinction matters.Distributors and partners looking to open accounts or secure exclusive regional distribution opportunities are encouraged to connect directly with Vetr’s wholesale team at wholesale@vetr.com.NOTE: This is sponsored content produced in partnership with Vetr

The Data is In: How Roaming Shortens Your Cat’s Lifespan

The bond cat parents share with their furry best friends is truly magical. Once viewed as a tool for rodent control, today they are beloved members of the family. As such, we naturally want them to live the longest, healthiest lives possible. However, recent research highlights a sobering reality: the simplest way to extend your cat’s life is also one of the most debated topics in the feline community. The secret to a long life? Keep your cat safely contained.  A comprehensive research review recently published in the journal “Global Ecology and Conservation” suggests that outdoor pet cats have a lifespan roughly two to three years shorter than those kept contained. While many of us imagine our cats enjoying a bit of freedom in the neighborhood, the data reveals a different reality. From road traffic accidents and territorial fights to accidental poisoning and infectious diseases like Feline Immunodeficiency Virus (FIV), the world beyond your property line is packed with hazards. Data shows that trauma is the leading cause of death and injury for free-roaming cats globally. In the UK, where free-roaming cats are more widely accepted, road accidents are the primary cause of death for cats aged one to eight. In fact, European estimates suggest that nearly one in four cats will be struck by a vehicle during their lifetime, and 70% of those incidents are fatal. Beyond the heartbreak of losing your best friend, roaming often leads to catastrophic vet bills. Cats that survive accidents or fights often face lifelong disabilities, abscesses, or chronic health conditions that require expensive ongoing care. This doesn’t mean all cat parents should be forced to keep their cats indoors 24/7. For those of us who believe that cats deserve to experience the sights, sounds, and smells of nature, there is a middle ground that doesn’t involve the risks of roaming. Transitioning to a “contained” lifestyle doesn’t mean your cat is sentenced to a life of watching birds strictly behind glass. The research explicitly supports a more modern approach to cat ownership, one that is also in line with the expectations placed on today’s dog parents: Catios: These enclosed outdoor spaces allow cats to enjoy fresh air and sunshine while remaining safe from predators, cars, and disease. They can range from a small window box to an enclosed patio space large enough for the cat and their people to hang out. Harness Training: Many cats can be trained to walk on a leash, providing mental stimulation and exercise under your direct supervision. Cat backpacks and strollers also allow cats to spend time in the fresh air safely. Secure Fencing: Installing fence-top rollers in your backyard can keep your cat within the safety of your property. However, it should be noted that this option will not protect your cat from overhead predators, like hawks. If your cat is spending more time inside, their environment needs to be enriched to match their natural instincts. Cats are vertical creatures. They thrive when they have access to cat trees, wall shelves, and high perches to survey their surroundings. Ultimately, keeping our cats contained isn’t about restriction; it’s about protection. By embracing the growing adventure cat lifestyle with leashes and catios, we can provide the experiences they crave while ensuring they stay by our sides for as many years as possible.
