1st of all Welcome to Yorkie Talk! You came to a great place for your questions.
I'm glad your breeder is keeping her dogs clean, cool, and socialized. Although those things are very, very important, there is so much more to breeding! As a breeder, I would like to list a few reasons why I personally would not purchase from this breeder:
1. Puppies she has purchased from other States, does not, in any way prove pedigree. If he had a pedigree, she would have proudly given you a copy of his pedigree when you purchased him.
2. Mixing her breeds. A responsible breeder would never mix breeds. We are trying to get the very best qualities in our Yorkies according to the Breed Standard as set forth by the Yorkshire Terrier Club of America.

3. "Breeding for just pets" makes me feel like a pet has to be substandard. Pets should be healthy, and as high quality as possible too. I want my Yorkie families to be proud of their babies, their qualities, and their health.
4. Breeding to tiny females is a big risk for the female. Almost guaranteeing C-Sections, Eclampsia (Low Calcium), Hypoglycemia, and Possible Death.
5. Anyone buying a whole litter is a, for lack of a better word.... a broker, although not admitting that this is what it really is. They purchase cheaper puppies and resell them at a much higher price. Brokers, or anyone purchasing several puppies, eventually purchase a diseased puppy that spreads the disease throughout their dogs and to unknowing families. It is inevitable!
6. A responsible breeder DOES care if you breed a couple of litters or not. We don't sell puppies with breeding rights, unless we have cleared the new owner for responsible breeding themselves.
These are all red flags to me personally. If you decide to breed your male, please have him genetically tested. Get your male's pedigree from AKC and research his ancestors for health issues. Use him responsibly. Check out the females you breed him to. If you stud, you are 1/2 responsible for creating the babies, make sure the other 1/2 is breeding for the right reasons.
You came to the right place for questions. We'll try to help in any way we can. If you want to breed, research, research, research.. and breed for the best! And Again, Welcome to Yorkie Talk!
