Dogs go through "ruff" times too, which means they also suffer from depression just like humans do.
Studies have shown that a dog's brain is similar to that of humans and thus feels like ours too.
According to research conducted by Dr Nicholas Dodman in 1980, dogs can also experience the chemical and hormonal changes that bring about depression and anxiety in humans.
Unfortunately, since dogs can't talk, pet owners will have to identify the symptoms and get them treated, the New York Post reported.
Dogs do not typically experience what we recognise as clinical depression in humans. However, they can certainly feel depression in the form of the blues, sadness and grief.
According to a 2016 study done on dogs, here are some signs to watch out for if you sense something is off:
