Omg! There are people out there who actually do that? Cross breed and then register them as a purebred??? I must be fairly naive about the purebred dog world….
Yes, there are, this person in AZ did it for years. As I remember not only was this person using Fox Terriers, but Whippets also since they competed in Lure Coursing. And has since stopped breeding due to health reasons, but the offspring of these dogs are still around and with papers and being used. It started as I remember (but Linda S can expand when she pops in since she is in that area were it happened) before AKC started with DNA requirements for breeding and since this is NOT a requirement unless you are a high volume breeder, it happens. Same with people that would breed a litter and use papers from a dog long dead or very old. It was then with older dogs that AKC put the requirement that on a dog over 12 there would be a sperm count requirement with any breeding. The DNA for parentage was done for high volume breeders (mostly for puppy mills and some BYB) was then also introduced.
In the case of these dogs, the first that I saw the pictures of her pups (Dayna in GA) I knew there was something different about them… and asked about the breeding. And a few years before this, there was a dog that she was using at stud that was a Brindle, however the pedigree of this dog indicated that there is no way this dog could be a Brindle. She had gotten that dog from another BYB in GA that was going out of business (Robyn from Sherwood Basenjis can expand on this when she pops into the Forum).
One reason that I think AKC should require DNA parentage for any and all breeding dogs.
