its because when your breeding crossbreeds your not breeding to a standard so you dont know what your going to get, and neither is the new puppy owners, which is why so many end up in shelters, they're not bred for a specific size, shape, look or temperament.

plus you cant register the pups so then if the pup's owners decide to breed they're going to be doing it blind as there'll be no papers so they cant study the lines and find out the health problems within them

i'm happy owning crossbreeds but i wouldnt breed them
