I have never had any dealings with the breeder personally, but there are several red flags on her site:
* She raises more than one breed of dog and purposely breeds designer dogs.
* She advertises tea cups.
* Describes the Yorkie-poo as a "breed," which it is not.

Not to mention she goes into great detail about the characteristics of the "breed", many of which are not even true!
Quite honestly, the gushing about how "Yorkie-Poos" are better and more intelligent than pure bred dogs makes me want to vomit.
