Signs of Depression in Dogs

Depressed dogs will usually give clues to their inner state through their behavior and, sometimes, through physical changes. We can't talk with our animals, so we must rely on these visual clues (along with veterinary checkups) to let us know when our dogs or other pets are not up to par. Signs of depression in dogs are similar to signs in humans; however, the signs may instead be a symptom of an underlying illness. For a professional assessment of the dog's condition, it's wise to get the pet to a veterinarian.

Physical Signs

According to vetinfo.com, common physical signs that a dog may be depressed are extra shedding, weight loss and lethargy. Weight loss usually occurs because the dog stops eating enough. Lethargy can be mild (the dog seems a little tired) or extreme (the dog seems to do little but sleep).

Little Interest in Food

When a dog suddenly loses interest in food, owners should pay attention. This is especially true if the lack of appetite lasts for more than 24 hours. It is not uncommon for pets to have temporary appetite loss. When it continues, however, the pet is either ill or unhappy.

Overeating

Like people, some dogs lose appetite when depressed while others, instead, have a large increase in appetite. If your dog is overeating, and exhibits other signs of unhappiness, he may very well be depressed.

Aggressive Behavior

Dogs that are usually mild-mannered but suddenly start acting out in aggressive ways (barking, growling or biting) may be depressed.

Shy Behavior

Depressed dogs that are normally outgoing may suddenly seem shy. Shy dogs may become more timid.

Considerations

The signs of depression, and depression itself, can be caused by illnesses--including diabetes, kidney disease, and heart disease. If your dog exhibits any depressive signs, he should be taken to a veterinarian for a checkup to rule out physical causes.

Depressed dogs, especially those that refuse to eat as much, may be more susceptible to illness and disease. Monitor your dog carefully. If you believe he is not getting enough calories, ask your vet if special high-caloric supplements are suitable.

Treatment

After your vet determines the dog is not otherwise ill, he or she may suggest an antidepressant for your dog. Other treatments include spending more time with your pet. If a recent household addition (new baby or new animals) or a move is the cause, your dog may simply need time (and a lot of affection) to adapt.
