Well, I did get two of my Yorkies from a supposed "reputable" breeder. They are both pet quality - not show dogs and the price was still very high. Just like anything else, I think the price goes up as the demand does. Because Yorkies are so popular now, people will pay huge amounts for one.
For the breeders reading this, I don't mean to offend or anything. Maybe you can justify for us the prices charged? Does it really take over $1,500 to raise a pup and still make a profit? Just curious since I've never bred dogs.
