The OP's question was about a reasonable price for a puppy, not whether to buy from a YT approved breeder! A 3000 dollar dog can be, or can get just as sick as a 600 dollar dog. Any dog can get sick at any time, the price paid does not buffer that possibility one bit. I see horror stories from "good breeders" here on YT quite often. That speaks volumes! You delude yourselves into thinking your 3000 dog is a "better dog". LOL! Get over yourselves, PLEASE!
Why not just answer the OP's question instead of giving a lecture on where to by a puppy?
~WOOF!
