I say this is a BROKER, just to many breeds and "Designer" pup, NO reputable breeder breeds mixed dogs. Brokers buy or sell on consignment puppies from BYB, Puppy Mills. Me, I would stay away. If you are considering buying based on price, well, as the saying goes,
"ya get what ya pay for"
Save more money, find a BREEDER not a broker, a breeder that has breeds just one breed not several diff. breeds. YT has a listing for breeders, check it out. Good luck on your quest for finding that healthy happy baby.
