[Amazing Yorkies]

I'm sorry it didn't work out for you and how hard it must be to let Hazel go back. But don't give up on a second baby. Sometimes a male works out better with a female, and also a younger one. I think the age of Hazel made her want to be alpha, and want you all to herself. A younger puppy usually just fits in better with an existing dog. Usually it is the existing Yorkie that doesn't allow someone invading their territory. It takes 2-3 weeks for things to settle down. With Sophie welcoming a new comer so easily, I wouldn't give up on adding another. I'm really sorry you have to return Hazel, it can be heart wrenching.
