I have a 12 week old Yorkie puppy (female) and a 6 year old female adult. The puppy doesn't know when to stop playing. She nips and bites the adult female and pulls her ears etc. Even though the adult Yorkie will growl, bark and even nip back, the puppy doesn't know when to stop. I have been using a spray bottle to get Pepper (the puppy) to stop and even remove Ellie (the adult) so that she doesn't have to deal with it. However, the only time there is peace is when they are sleeping together. Does anyone have any suggestions?
