Chasing their tail
You may tease your pup for chasing something he will likely not catch. More so, if he does catch it, it’s getting to be painful! Puppies do that because they’re doing not realize the thing they are chasing is already theirs. Other dogs do that once they are in a confined space or feeling bored. Check your dog for fleas or have his anal glands checked if he does this regularly, it might be a symbol of a drag.
