Up to 10 percent of humans experience mild to moderate seasonal depression. But can dogs and cats catch the winter blues? Learn how cold weather can affect your pet’s mood and what you can do to lift their spirits this season.
 

What is Seasonal Affective Disorder in Pets?

Seasonal depression, or seasonal affective disorder (SAD), is a form of depression commonly diagnosed in humans. SAD, or seasonal depression, is not formally recognized in pets, but some pet parents observe changes in their pet’s mood and behavior during the winter months. SAD is characterized by symptoms that resolve when warm weather returns.
 

What May Cause Seasonal Depression Symptoms in Pets?

It’s not known what causes symptoms of seasonal depression in humans, let alone pets. The phenomenon is commonly linked to shorter days, leading to reduced exposure to sunlight.

Sunlight suppresses the production of melatonin, the hormone that influences our sleep-wake cycle. Short, cold, cloudy days can mean you and your pets produce more melatonin, which could explain why your pets may seem less energetic in the winter. Though cold weather may make your pet want to curl up and sleep all day, it does not necessarily mean they are depressed.

Low sunlight exposure also influences hormones that control appetite and metabolism. Naturally, animals in the wild need to consume more calories to survive harsh winter conditions. While your pet may have a more ravenous appetite in the winter or may seem more prone to packing on pounds, this is likely a result of seasonal hormonal changes rather than emotional eating due to winter depression.

What we may perceive as symptoms of seasonal depression in pets are often natural processes that their body goes through in response to cold weather. While dogs and cats do not hibernate, it’s absolutely normal for them to slow down in the winter.

Sometimes, perceived symptoms can be a reflection of our own mental well-being. Rest assured that if you are struggling with SAD, you do not have to worry about passing depression to your pet. Your dog or cat will be content to snuggle by your side through the seasons of life. That said, if you’re having trouble caring for your pet or yourself this winter, reach out to a friend, family member, or mental health resources for support.
 

Keep Pets Active To Fight Winter Blues

Though keeping your pet active in the winter can be a challenge, finding ways to play, train, and bond with indoor activities can benefit both you and your pets when it’s frightfully cold out.

Dogs, in particular, may struggle with a lack of walks and outdoor activities in the winter.

“They may lay by the front door wanting to go outside and stare at you with sad eyes, but this doesn't mean they are depressed,” says PetMeds ® Expert Dr. Lindsay Butzer, DVM.

“Dogs love our affection and time. If you don’t want to walk with your dogs outside because it is dark and scary or even reasonably so dangerous, then you can train them indoors for 10-15 minutes for mental stimulation. This will make those sad eyes go away. Or even laying on the couch with them to watch a movie will make them happy.”
 

Other Causes of Depression Symptoms in Pets

Any time you notice a change in your pet’s mood, appetite, or behavior, you should consult your veterinarian to rule out an underlying health issue. What might be perceived as seasonal depression could be a symptom of pain or discomfort.

• Osteoarthritis is exacerbated by cold weather. A pet that hesitates to get up and play could be suffering from joint pain and stiffness. See your veterinarian for a diagnosis and pain management.
• Endocrine conditions like diabetes or Cushing’s disease can cause changes in appetite and energy levels.
• Anxiety can be exacerbated by a lack of exercise due to inclement weather or changes in your household or schedule.

If your pet’s symptoms persist or worsen, see your vet or make a same-day online appointment with VetLive.
