Yorkshire Terrier Information About Yorkies, Yorkie Yorkshire Terriers
She is close to U of M...so I assume Ann Arbor area and she's a show breeder. I absolutely love her website because it's very informative and it looks like she's got some beautiful dogs.
There are lots of BYB's around MI...please make sure you do your research and buy a pup from a reputable breeder.
There are also LOTS of rescue yorkies on petfinder in our area. You will find everything from small puppies to older dogs on there...may be worth a look.
