Welcome to YT! If you want to be an educated buyer and buy a healthy happy yorkie, please do your research. You buy your breeder first and a good breeder puts all the dogs health first, which includes parents and pups. There is a lot of good reading material for future yorkie moms and dads. You can find it in the "Yorkies for sale" forum. If you can't find it, let me know and I'll post links for you. Please be careful of where you purchase your pups from. Good luck on your search.
