Kitty she didn't start the distrutiveness till after my mother gave her dog away. Thats when it all started but the minute another dog is brought into the house shes fine. I know this because we watch my grandparents tea cup yorkie alot and she loves when he there because she wants to play with him but she can't because he is about 11 years old. LOL She always seems to get along better with puppys then bigger dogs. The puppys and a golden retriever are the only dogs that she plays at when it comes to the dog park. She use to play more but once Loki left and she started going up there alone she won't play that often she just follows me around and if I sit down she will lay down next to me. I hope this makes since.
