I recently bought a pup whom I foolishly took home without the paperwork. I trusted Top Dogg Giant Schnauzers. 2 months later after asking I get the paperwork. To my surprise the AKC Litter Certificates says my pups parents AND the grandparents were brother and sister from same litter. Upon contacting AKC they said they do not have a policy on "inbreeding" they leave that up to the discretion of the breeders. Really! Doesn't that increase the chances of the pups from such a litter being genetic cesspools? Buy a pup from a breeder that has a "Genetic" and "Health" guarantee.
