I got prince from Coffee Creek Kennel I believe they are in Ok.
Here is a link to the yorkies they have available

I havent had any problems with prince except ear infections but that was my fault for not keeping his ears plucked.
I had a wonderful experience with them as breeders and they certainly do care about their babies.
When prince arrived at the airport, he was just as chipper as could be. Full of energy, kisses, and love.
Let us know who you decide to go with and how it turns out!
