I have been reading so mnay negative comments about breeding cross breeds. Why? To be honest, I am as open to owning a mongrol as a pedigree???

a few members in particular apear to have a real problme with breeding dogs that aren't purebred or crossing breeds. I just can't understand it. If the dog and bitch are healthy and ready, and the same steps taken as breeding a pedigree e.g health tests/findg homes first - i really can't see a real issue...
