Dogs and seasonal affective disorder.

Back to dogs!

After yesterday’s giant essay I return to something to do with dogs. Albeit, a subject that is in the range of controversial – seasonal affective disorder. As published by Mother Nature Network.


Can pets get seasonal affective disorder?

Winter can be as hard on pets as it is on people.

During the shorter, darker days of winter many of us turn lethargic and gloomy. But seasonal affective disorder (SAD) isn’t just a human affliction. The animals we share our lives with may also suffer from something akin to the “winter blues.”

Here’s what experts know about SAD in pets and what you can do to alleviate it. (Hint: Some of the same things that counteract seasonal depression in people also work for our four-legged companions.)

SAD pets

Starting in fall as the days get shorter and sunlight levels decline, many people notice their mood begins to dip. According to the National Institute of Mental Health, SAD isn’t just a weather-related funk, but a type of depression that fluctuates with the seasons and causes unpleasant symptoms like sluggishness, increased appetite, depression, social withdrawal and even suicidal thoughts in the most severe cases. It’s believed that lower light levels prompt a decline in the feel-good brain hormone serotonin and boost the sleep-inducing hormone melatonin.

No surprise then that pets, with their similar brain chemistry, may also suffer from the same kind of seasonal hormonal havoc.

Not a lot of research has been done on pets, but a survey by a veterinary charity in the U.K. called the People’s Dispensary for Sick Animals (PDSA) found that one in three dog owners noticed their pooch seemed down during the winter months. Symptoms ranged from aggressive behavior, inappropriate soiling and less interest in going for walks to lethargy, demand for more attention and increased sleep.

Cats also apparently get the winter blues. One-third of cat owners in the same survey said their felines seemed glum in the winter and about one-quarter said their pet ate more.

Is it real?

There’s plenty of evidence that animals suffer from physical afflictions related to seasonal sun deprivation. One is called light responsive alopecia (fur loss that occurs in certain dog breeds during the winter months). But there’s not yet any hard science on whether pets actually experience SAD. Remember, the U.K. study was subjective, based on pet owners’ perceptions rather than rigorous research.

One alternate explanation for SAD-like symptoms in cats and dogs is that they’re picking up on the blue moods of their owners. Studies show that dogs, in particular, recognize human emotions and respond to them.

Or perhaps pets are merely bored during the winter months when they can’t get outside as much. Lack of physical and mental stimulation may push them into listlessness.

Whether pets are prone to SAD like humans are or they slip into a seasonal slump for other reasons, there are ways to keep their spirits high during the chilly season. In fact, the same fixes that help people beat winter depression might also help their animal companions maintain a brighter mood. Here are some simple things you and your pet can try together.

More indoor light. Open your curtains and shades during the day to let in natural light. Position your pet’s bed near a sunny window and be sure to hang out there, too. Also consider light therapy that mimics sunlight. Buy a full-spectrum light box that covers the electromagnetic spectrum from infrared to near-ultraviolet and plant yourself and your pet in front of it for 30 to 60 minutes a day.

Spend quality indoor time together. Engage your pet more when you’re inside during the winter months with new toys, extra play and increased cuddle time. Multitask by enjoying these activities in front of the light box.

Enjoy the outdoors. Take advantage of mood-boosting sunny days by letting your pet go outside during peak daylight hours. Better yet, join in for a romp in the yard or a walk in the park (cats can be leash trained). Outdoor time has the added advantage of allowing pets (and you) to exercise, take in stimulating neighborhood sights and socialize with other people and animals. All are known blues busters.


Whether or not pets suffer from this disorder isn’t really known, “Whether pets are prone to SAD like humans are or they slip into a seasonal slump for other reasons, ” the fact remains that the winter months for some dogs do have the cause to provide a slump. Whether you have one pets or quite a few, keep a close watch of them and love them through and through.

  1. Wow. Live and learn. I had no idea that SAD could also affect animals, although why not if we have similar brain chemistry. Years ago I took care of an aging aunt who suffered from Alzheimer’s. We had always been close and before she became afflicted, I remembered her saying how she felt so down in the winter time. Because I feared for worse symptoms with her dementia, I bought her some of those full spectrum lights. They seemed to help and she did not decline further in the winters, So, I think that is a very good suggestion if you have a pet with SAD. Really useful post.


    1. That full-spectrum light may be worth considering for here. It’s an idea. Not for the dogs necessarily but for the people! Your experience with your Aunt, Tony, is very good lesson. I am not as sharp as I used to be!

      1. Regarding the full spectrum lights, don’t use them late in the evening or you will have problems getting to sleep. Your body will be thinking it it still daytime.


      2. I don’t think so, but to be honest it was a number of years ago that I got them. Check Amazon. I’m sure you can at least get a price. Good luck!


      3. A couple of further observations on the lights. First, I do use mine at night, but I wear sun glasses. That way, i can go to sleep with no problem afterwards.
        Second, on the idea of light. I don’t know if this is relevant to you, but I know that I am affected by dreary overcast days. When I drive, I wear amber, night-driving glasses on overcast days. I feel they lift my spirit markedly from just driving without them.


  2. Ray is highly routine driven (aren’t we all?), so planning ahead to accommodate the clock changes in Spring and Fall are important. In fact Ray is going to see his favorite vet soon and must fast! We are already slowing pushing his breakfast time back so that on “the day”, he will not be wondering what happened to it!
    He also loves the colder weather, so SAD as a result of this time of year are not obvious with him. He is not so happy in the hot and humid summer, but then his walks are either to some water, or are kept short.
    No doubt SAD is prevalent with many dogs, but it can probably be minimized if the owners see the world from their dog’s perspective, and plan accordingly.


      1. Serious or not remains to be seen. He has a small blister like growth on his upper jaw which is going to be analyzed (biopsy), and we are taking advantage of the circumstances (anesthetic) to have all his teeth thoroughly checked.
