I have obviously been labled as a bad breeder because my first liter of puppies coming in a month are 3/4 razor's edge and 1/4 colby pit. under the ckc registry. now I love the pitbull breed and I dont wanna put this breed in danger no more then the next person. so if someone could explain to me what a good breed is, what the best blood lines are for a small breeder like my self. and why because quite frankly i didnt think i was committing a crime here.
