Nipping and Biting- Dogs and puppies
Most puppies will mouth things, including your fingers, when they are very young. This will progress to a nip. Mouthing is
normal behaviour in the young as they learn with their mouth and nose. Nipping is the first step in learning dominance. It is not amusing; stop it immediately, by a sharp reaction- the “No” it has already learned- and a tap if necessary. Remember your pack leader role!
