Help! My 11 month old beagle keeps biting my 8 week old Shepard’s ears!! He’s playing but he’s roughs and fast. I’m afraid of the way he bites and runs away he may tear the Shepard’s ears or break down the cartilage so they don’t stand up. I don’t know what to do to stop him. I don’t want him to think I’m telling him “no” for playing. Any suggestions would be very appreciated!
