I try to set a price that will offset my out of pocket costs as much as possible--vaccinations, medical care (including pre-natal for the mother) time, food, supplies...geez the list goes on and on. I also try to stay with what prices in the area are. I don't want to be the bottom because my opinion is the millers and people out to get hte cheapest Yorkie they can find will be calling.
You're prices are just that YOU'RE prices....and NO, they do not seem unreasonable to me.
