Baxter sounds awesome
my Suzi is full of energy too, and into everything .She is a puppy, and I love her antics. I have birds, and sometimes she jsut barks and barks at them... My birds are real devils though, and will nip at her... I have to watch them more, and they ARE louder then Suzi!
I am glad your big dog tolerates your little Yorkie, but, I would not take a chance of ever leaving them alone.
Your little guy feels like a big dog, and is not afraide to act tough and daring. They have a heart of a lion.
