Pets, like humans, also have emotions. We can simply judge their positive emotions based on their behavior, but when they have negative emotions, how do they express them?

Reason 1: Medical pain

Dog depression may be medically related. The pain caused during medical treatment may cause depression in dogs. It is necessary to observe the emotional changes of dogs in daily life.

Reason 2: Environmental changes

If the living environment suddenly changes, such as being sent to the owner's friend's home for foster care, or the owner's family moving to a new house, the pet will generally show a little discomfort and feel at a loss.

Of course, if the owner has a new baby, the puppy may be jealous~

Reason 3: Separation anxiety

People who are separated from their pet owners will feel very uneasy, nervous and even depressed when the owner leaves home without taking them out.
