Hi....I paid $850 for my little man and I got him from an excellent breeder. This breeder always kept me up-to-date every week with pictures and videos. Remy was the runt of the little and she was very picky of whose home he was going to live in. Remy's two sisters definitely got all the milk & food.
She asked me all kinds of questions. She was worried about small children with him which she didn't have to worry because my two children are grown and out on their own. She kept him with her until he was 4 mths old so he could gain more weight. We still communicate and I send pictures to her to keep her updated. My daughter's yorkie cost $1800 three years ago and my sister's yorkie cost $3000 three years ago. All three came from reputable breeders. None of the dogs have any medical issues....thank goodness. So all in all, it is a matter of doing your homework on the breeders and their dogs, asking the proper questions, etc.
I hope this helps.
