Can Dogs and Cats Get Seasonal Depression?

In humans, seasonal affective disorder is a type of depression that correlates to the change in seasons, usually winter, says Kandace L. Nollie, LMHC, a licensed mental health counselor and program director at Chrysalis Health in Brandon, Florida.  

While the exact cause can vary and is often unknown, it can sometimes be caused by changes in sunlight, sleep patterns, and shifting levels of melatonin, a chemical that affects sleep. 

If you’ve wondered if pets can be affected by seasonal depression like humans, the truth is that there’s not much research on the subject yet.  

But if your pup seems more sluggish and sleepy once winter sets in, SAD could be at play, says Dr. Ahn.  

“Dogs’ behavioral changes observed during the winter months may very well be attributed to an increase in melatonin due to the shorter daytime hours, which has been linked with SAD in humans,” he explains.  

And cats can be affected too. Dr. Ahn says the most common signs of SAD in both cats and dogs are: 

• Lethargy  
• Loss of appetite  
• Overgrooming  
• Excessive vocalizing  
• Oversleeping  
• Weight gain  

If you’ve noticed a change in your pet’s behavior, call your vet. They’ll rule out other health conditions before looking at your pet’s emotional health.  

Dr. Ahn notes that diagnosing SAD in pets can be a challenge. After all, our dogs and cats can’t verbalize how they’re feeling. But your vet will listen to your concerns, evaluate your dog or cat, and, if necessary, suggest treatment. 

“Whether SAD is to blame or not, mood and behavior changes are very real,” says Dr. Ahn. 

While treating seasonal depression in people can include therapy or medication, treating your pet’s winter blues might revolve around simple lifestyle changes. 

Open blinds to let the sun in and turn on lights in rooms where your pet often hangs out. Adding more sunlight can help elevate mood-boosting serotonin and decrease melatonin, which can make your pet sleepier. 

If it’s warm enough for your dog, take a walk or hike outdoors. Dr. Ahn says the change of scenery, fresh air, natural light, and movement is great medicine—if you’re prepared.    

Make sure your dog is winter-ready with a warm sweater or coat. The Frisco Western Pattern Dog & Cat Sweater and the GF Pet Reversible Chalet Dog Jacket are great options.   

Your pup will also need a cute pair of weather-appropriate booties, like the FinNero Halla Reflective Soft Fleece Dog Booties. Paw balm, like Natural Dog Company PawTection Dog Paw Protector Balm, can be helpful to avoid dry, cracked skin.   

For cats, getting closer to nature might mean having a perfect perch in a sunny window with a view of your backyard. Try the K&H Pet Products Deluxe Kitty Sill Cat Window Perch or the Frisco Plush Cat Window Perch with Removeable Bolster.  

A cheery cat tree, like the Tscomon 55-in Plush Cat Tree with Hammock, Toy, & Sisal Scratching Post, in a sunny spot can also be a mood booster. 

If it’s not too cold for your cat, you could also allow them into a catio, like the beeNbkks Cat Catio Window Cat Perch, for some fresh air.  

If your vet gives the green light, a supplement might be a good fit for your dog or cat to help with winter blues.   

Try an omega-3 supplement with fish oil, like Zesty Paws Wild Alaskan Omega-3 Salmon Oil Liquid Skin & Coat Supplement for Dogs & Cats, to give your cat or dog’s brain a happy little boost.  

Games can also help to keep pets stimulated and active, reducing the chances of winter depression. Try a fun hide-and-seek toy for your dog, like the Frisco Volcano & Dinosaurs Hide & Seek Puzzle Plush Squeaky Dog Toy, or a puzzle toy, like the Brightkins Kanoodle Puzzle Dog Toy.  

Cats will also appreciate a puzzle toy, like the Nina Ottosson by Outward Hound Rainy Day Puzzle & Play Cat Toy, or a feather wand to chase. Try the PawsPik Interactive Hide & Seek Concealed Feather Cat Toy, which has extra features to keep them entertained.
