He also has a groomer. My mom uses her for her dogs. She is really good with the dogs. I think her name was Yoily something like that. Our new Yorkie has not had the chance to go to her yet but she will when her hair grows out some more.
A really net pet park to take your Yorkie to is McAllister Dog Park.
