Hi - My name is Linda and I've never posted on here before. I have a question about my little girl, Isabella. She is an anxious one and even hid from all the other small dogs in her first training class. She's very fearful even after going through positive reinforcement training with a specialist. My question however is if anyone else has a Yorkie that can recognize another Yorkie? She won't play with any other dogs unless she sees another Yorkie and then she goes crazy, running in circles, tail wagging, trying to play chase. No other dog will she do this with, only another Yorkie. How in the heck does she know it's really another Yorkie? Thanks for any responses.
