You might notice your usually playful pup getting quieter during the colder, darker months. Maybe they sleep more, seem less enthusiastic about walks, or just don’t have their usual spark. As pet parents, it’s only natural to wonder—can dogs actually experience seasonal depression?
At 108 Avenue Animal Hospital, we hear this question often, especially from concerned dog owners during the fall and winter. While “seasonal depression” in dogs isn’t officially recognized as a clinical diagnosis, science does suggest that seasonal changes can affect your dog’s mood, behavior, and energy levels.
How Shorter Days Can Impact Your Dog’s Behavior
Light has a powerful effect on living beings, and dogs are no exception. Just like in humans, reduced daylight in the fall and winter can disrupt your dog’s circadian rhythm—their internal body clock that regulates sleep, hormones, and energy levels.
Less sunlight can lead to lower serotonin production, which is often linked to mood changes. Some studies have shown that dogs exposed to fewer hours of natural light may display signs of lethargy, reduced appetite, or increased clinginess.
At 108 Avenue Animal Hospital, we’ve noticed that some pets brought in during the colder months show patterns of behavior that improve again in spring. While not every dog is affected, some are definitely more sensitive to the seasons than others.
Signs Your Dog Might Be Feeling Down
So what should you watch for? Here are a few subtle signs that your dog may be experiencing a seasonal slump:
- Sleeping more than usual
- Decreased interest in toys or playtime
- Eating less (or occasionally eating more)
- Withdrawing from family members or becoming overly attached
- Reluctance to go outside or on walks
- Changes in bathroom habits
If your dog’s behavior changes for more than a week or two, or if they seem truly down or unwell, it’s always a good idea to check in with your vet. A physical health issue could be hiding behind those low-energy days, and we can help rule that out at 108 Avenue Animal Hospital.
What You Can Do To Boost Your Dog’s Mood In Gloomy Seasons
While you can’t control the weather, there are simple ways to help your dog feel better during shorter, darker days:
- Stick to a routine: Dogs thrive on structure, so keeping meal and walk times consistent can help ground them.
- Maximize daylight: Take your walks during the brightest part of the day, even if it’s cold. Sunlight—even a little—helps regulate mood.
- Keep them mentally stimulated: Use puzzle toys, training sessions, or indoor games to engage their brain.
- Add extra playtime: Movement releases feel-good chemicals that help lift mood, just like in humans.
- Consider a light therapy box: While research in pets is still emerging, some pet owners report positive effects using light boxes near resting areas.
If you’re not sure where to start, or if your dog’s mood seems off despite your best efforts, we’re happy to help. At 108 Avenue Animal Hospital, we offer personalized wellness plans and behavioral support to keep your pet emotionally and physically healthy all year long.
When To Talk To A Vet About Seasonal Changes
While mild seasonal mood shifts can be managed at home, it’s important to involve your veterinarian if you notice any prolonged behavior change. Things like thyroid imbalances, arthritis (worse in colder months), or chronic pain can also mimic signs of depression.
