Although our furry friends and beloved companions do not have this option, it does not mean that they cannot feel sad or depressed.

Some stories seem obvious, as a dog suddenly chooses to sleep all day in the back of the closet after the death of another dog in the house. But some signs are not specific, where dog owners may notice a change in their behavior.
So, how do you know if your dog is dealing with canine depression? Here are a few common symptoms – many of which are similar to the symptoms of depression in humans.
Food Cravings
When dogs are overweight, they lose interest in food and tend to lose weight. Alternatively, some dogs seem to use food as a form of comfort when they are stressed and want to eat more, which leads to weight gain.
Sleep for a Prolonged Period
If you leave your dog alone for a long time and it continues to sleep after you get home, and does not respond to you, there is probably something wrong. Look at the physical problems first, but if you do not get anything and the symptoms persist, he may become depressed.
Loss of Interest
If your dog suddenly loses interest in playing and doing things that make him happy, it’s time to pay attention to your dog’s call for help. Dogs that are inactive and slow-moving, may suffer from canine depression.
Licking Paw
Excessive licking of paws or chewing may be a sign of physical or mental problems as depressed dogs often lick or chew their paws.
Avoidance and Concealment
Dogs that suddenly hide or want to be left alone should be taken care of as something bothers them. If not physically, it may be emotional.

Often, emotional issues are based on physical and medical causes. The first thing to do if you notice a behavior change is to have your pup or dog checked by your vet before coming to any conclusions.
