Pet parents have asked me if dogs can experience depression. In almost every case, the question is prompted by troubling behavior and not just simple curiosity. Well, dogs can most certainly exhibit obvious signs of depression, such as loss of appetite or declining interest in previously enjoyed activities. And then there are symptoms not readily recognized as depressive: anxiety, fearfulness, aggression, various destructive behaviors and even hiding from people. Are these last signs indicative of depression, a complicated emotional disturbance, or do they point to something else altogether? 

In humans, depression ranges from temporary episodes of sadness to severe, persistent clinical depression, which persists for significant periods of time. Both are marked by a depressed mood and a loss of interest and lack of pleasure.

Dogs are highly intelligent, emotional creatures. We know that they can read our facial expressions, learn complex commands, express fear and joy, and can get stressed, but can they be depressed? Behavioral scientists not only say ‘yes’, but are surprised by how prevalent depression is among canines. In fact, in a 2013 British study, scientists discovered something shocking … nearly one in four dogs in the UK was suffering from some form of depression.

Because we cannot simply ask our dogs if they’re depressed, how can we know for sure what’s going on? Well, the experts say, look to sudden changes in behavior which cannot be attributed to a medical problem. In such cases, depression offers the most logical rationale. But, on an emotional level, we also have our own sense of empathy as a guide. As pet parents, we often just intuitively know something’s up.

MORE ON SYMPTOMS

Canines often express signs of depression after loss of a family member, whether it’s a human or another animal. When someone close to a dog is no longer around, they can be listless, lose their appetite, be cranky, pace frantically, regress in house-training, sleep for even longer periods, and even develop destructive behaviors such as digging or chewing. Some dogs can develop anxiety-ridden behaviors, such as prolonged trembling, while others experience a significant change in personality (outgoing, becoming withdrawn and distrustful).

MORE ON CAUSES

Some dogs can exhibit depressive behaviors if they don’t get enough exercise or attention. Even changes in routine, ranging from serious (loss of a caretaker) to the seemingly harmless (changing a pet’s bed) can result in the symptoms listed above.

Unfortunately, changes in behavior can signal an underlying medical problem. Painful conditions such as arthritis, pinched nerves, bladder infections, or gastrointestinal inflammation can elicit behavioral changes, and hormonal conditions such as hypothyroidism can mimic the signs of depression in dogs. If you notice any sudden changes in your dog’s behavior, schedule an appointment with your veterinarian. With a physical exam, and any necessary tests administered as warranted (such as blood work, urine testing and x-rays), your vet will be better equipped to determine potential causes and likely treatments.

HOW TO DEAL WITH YOUR DOG’S DEPRESSION

If your dog seems inordinately sad or becomes listless, you do have some options for home therapy.

Be intentional about the time you spend with your dog. Be prepared to dote on your pup, (yes, even more than usual!), and shower them with attention, like you would with a newly adopted dog.

Renew your commitment to exercise with daily walks … sunshine and fresh air can do wonders for both you and your dog. Plus, you’ll be adding a little adventure to your dog’s day. By taking long but unhurried walks, you allow your dog the time and space to roam a bit and smell all the scents. Remember, they can detect a whole host of odors, building timelines and creating mental maps of previous activity in any given spot … think of it like canine storytelling.

While at home, make sure your pup has plenty of good chew toys, and engage in some training sessions to stimulate positive mental activity.

In spite of all this, if your dog is still experiencing chronic depression, your veterinarian can recommend an appropriate medication to help manage, possibly even resolve, the illness. Your vet may recommend a consult with a board-certified veterinarian behaviorist. Certified by the American College of Veterinary Behaviorists, these experts are especially good at understanding such situations and knowing which pharmaceuticals will be most effective.

Have you ever known a canine who suffered from depression? How did you know? And what, if anything, were you able to do to help alleviate the condition? We’d really like to know about your experience, so please submit your comments below. You never know … something you share might mean the world to a pet parent searching for a solution, even if it’s simply the solace of knowing others have dealt with similar issues.

Thank you for all you do to make the world a better place for companion animals.
