I got a retired female breeder from her and I have absolutely no complaints. The transaction went as planned, and the dog arrived safely and on time, and was as she described. All paperwork was in order and we still stay in touch. She's very knowledgeable of her breeding lines and gives a health guarantee with her puppies. I would definitely purchase from her again. There are a few YT'ers who have purchased from her and are happy and return customers. Her website is very informative also.
