I recently bought a four-month old Shih Tzu; our Jack Russell is five years old and shows hostility. I've read in different forums that JRs have a tendency to be dominant towards animals and other dogs of a smaller size. Both dogs are female and neither is spayed, but our JR continuously tries to bite or shove our Shih Tzu and refuses to stop barking. We've tried using a muzzle but she still shoves the younger puppy. I'm afraid that our JR will seriously harm the puppy- will this behaviour stop?
