How Season Changes Can Affect Your Pets (and What You Can Do About It)

Just like us, our furry (or feathery or scaly) companions can feel the shift when the seasons change.
While they may not be reaching for pumpkin spice lattes or sunscreen, pets are surprisingly sensitive to changes in weather, daylight, and temperature.
Understanding how these changes affect them can help you keep your pet comfortable, healthy, and happy year-round.

1. Temperature changes
In colder months, pets with short coats, small bodies, or thin fur may get chilly fast. Cats might start seeking warm corners, while dogs could be less enthusiastic about their morning walks. Arthritis symptoms in older pets also tend to worsen in the cold, making movement more difficult for them.
In warmer months, pets can quickly overheat. Dogs, in particular, are prone to heatstroke because they don’t sweat the way we do. Flat-faced breeds like Pugs and Bulldogs are especially vulnerable. Cats tend to find the coolest place in the house and hibernate during heat waves.
What you can do:
- Adjust their bedding or clothing. Sweaters and heated beds for winter; cooling mats and plenty of shade in summer.
- Keep walks shorter in extreme temps, and keep away from hot pavements in summer.
- Always provide fresh water and never leave pets in a hot car.
2. Allergies and skin irritations
Spring often brings seasonal allergies, and not just for humans. Dogs and cats can suffer from itchy skin, watery eyes, and sneezing due to pollen.
What you can do:
- Wipe down paws after walks to remove pollen.
- Consider pet-safe anti-histamines (always check with your vet first).
- Bathe them regularly with soothing, hypoallergenic shampoos.
3. Changes in daylight and behavior
As daylight hours change, your pet's internal clock can shift too. Some pets become more lethargic in the winter, especially indoor cats who bask in windows during the sunnier months. Others may experience changes in mood, appetite, or sleep patterns.
What you can do:
- Keep a consistent routine with feeding, walks, and playtime.
- Keep the lights on and bright during dark winter days.
- Add a few extra play sessions to keep spirits up.
4. Shedding and coat changes
Many dogs and cats "blow their coats" in the spring and fall, shedding their winter undercoat or preparing for colder months. This is perfectly natural but can leave your home looking like a fur storm just hit.
What you can do:
- Brush your pet frequently— daily, if needed, during peak shedding.
- Use de-shedding tools or grooming gloves.
- Regular grooming helps reduce hairballs (especially for long-haired cats).
5. Pest problems
Fleas, ticks, and mosquitoes come out to play when the weather warms up. These pests can transmit diseases like Lyme, heartworm, or even tapeworms.
What you can do:
- Keep up with year-round flea/tick prevention, even in winter (some pests survive indoors!)
- Check for ticks after outdoor adventures.
- Ask your vet about heartworm medication, especially if you live in a warmer climate.
Final thoughts
Season changes affect your pets more than you might think. Being aware of how temperature, daylight, allergens, and pests can impact them helps you adjust their care throughout the year.
