Sometimes I like to peek in my local pennysaver & see the yorkie puppies for sale (mostly by backyard breeders unfortunately)...once in a while, I'll come up to an ad that just doesn't make sense to me. It's for a stud service, a yorkie...7 lbs! Most of us know that you should always breed a female to a tinier male...They want $300 for his stud services.
Let's leave it to the reputable breeders & show professionals.
