Designer breeds all look different, they are mutts so there is no standard. Often times backyard breeders that produce deisgner breeds will say that they are "unique" and that is why they are so expensive. Every dog is unique! And every mixed breed looks different! I don't understand why people will shell out a crazy amount of money to buy a designer breed, when there are plenty of unique mixed breeds at your local shelter.

Good luck with the dog you want at the shelter!
