Yes, my nieces' 2 yorkies are about 3 months old. They are so wild, running around and biting each other's ears. They are currently being crate trained. Yeah, maybe chin chin is teaching them matters or he doesn't like to be picked on and biting his ears by the two yorkies. However, when I walk him out on the streets, he doesn't like to sniff other dogs and hide behind my legs. Shinobi, however, likes to play with other dogs. What should I do with Chin Chin?
