Yes, she does breed peke a poohs too, but she does not mix them with her Yorkies. I asked about the other dogs and she has a boy peke a pooh breed with a girl peke a pooh. They are kept in separate places then with the Yorkies. My Mom checked it out 2 years ago and has been to her house 4 different times over the years. She said that all the dogs are well cared for and looked in good health. I will be going and checking her out myself.
Thanks for the information and I will keep it in mind!
