We have a Yorkie, Rusty, and he is 14 years old. He grew up with a Boxer(Jake) who passed in 2007. He now lives with 2 French Bulldogs and gets along fine. He is the old man and the boss. Our cream Frenchie (Bere) thinks that he can intimidate Rusty once in a while and soon learns that Rusty is still the boss. We do love our fur babies. :thumbup:
