No, a Pomeranian does not bite. Pomeranians are not an aggressive breed. However, like most breeds, as puppies they will bite and nip when play-fighting or just exercising their jaws.
Their little teeth can be quite sharp, so it’s important to discourage this behavior to prevent it becoming a bad habit. When your Pomeranian nips you, end the game immediately and ignore your Pomeranian. He’ll soon get the message that biting isn’t a smart way to play and find a better way to have fun with you.
