Melatonin is a hormone produced in the body that can cause depression or sleeplessness if its levels are too low, but it also has a minor sedative effect on dogs.

It isn’t safe in some dogs with preexisting conditions, necessitating the approval of your vet before you start popping pills into your dog.

What Can You Give Dogs for Anxiety?
