You can check your shelter or rescues or petfinder but please be sure you can afford care and the thousands (and thousands) it will take for any likely medical problems. They are more and more common as there are more and more irresponsible breeder's (there are plenty of dogs in the shelter's and rescue's for this reason as well).
