Update question: American vs. English Bulldog DNA testing?

Question

I recently posted a question regarding American Bulldog vs. Bulldog (for those of you who freak when someone uses the term “English Bulldog” just so people aren’t confused) scientific (DNA) differentiation within breed tests.

I’d like to first say that I didn’t find what I was looking for. I only wanted to know if anyone found a test out there that I hadn’t. No one did. Everyone spent their time instead ranting over my terminology, assuming that I purchased a puppy without major research into the breeder nor actually viewing the entire litter, the Dam, and the Sire. Some also went as far as to call me names and accuse me of being yet another who ignorantly added to the population of mixed, registered, purebred dogs out there.

As for my question, let me state more clearly...First, I know that “English Bulldog” is not correct terminology. I put it that way so that there were no questions as to what type of bulldog I was speaking of. Second, I SAW THE PARENT DOGS so there's no need to get a picture nor do I need to research what an American Bulldog, "English" Bulldog, Pitbull, French Bulldog, etc., etc. look like. I know. I've owned both ENGLISH & AMERICAN BULLDOGS, had grandparents who owned French Bulldogs and used to know some people who owned Pitbulls. Probably any breed of any type of bull dog variation I've known one personally. I'm fully aware of both breeds that I brought up (American Bulldog & Bulldog) and their major differences. I went to the breeder's home and saw the entire litter, registration papers, and all other possible info you could think of when considering buying any purebred puppy especially one of such cost and possible health needs.

Again. I'm aware that I need to do a DNA (breed and/or parentage test) on my puppy, the male supposed to be his father, and the female. My question wasn’t “someone please tell me stuff I already know and/or how might I determine if my dog has any other breed in him”. MY QUESTION IS AND WAS: I NEED A TEST TO SCIENTIFICALLY DETERMINE IF MY DOG IS PUREBRED AND I HAVEN'T FOUND ONE. ANYONE KNOW OF ONE THAT DIFFERENTIATES BETWEEN BULLDOG AND ALL THE RELATED BREEDS? IF THE BREED TEST ONLY LISTS "BULLDOG" AND "FRENCH BULLDOG", how in the world am I to know if the test determines "BULLDOG" as what is actually bulldog, or does that term also include american, pitbull, and other breeds with the name bull in it. I'm asking all of you because the representatives at the company that makes and runs the tests don't know the answer to that question. They’re not sure if their test can differentiate scientifically between breeds of Bulldog relation such as Bulldog (English), American Bulldog, Pitbull, Bull Mastiff, Bulldogge, Alapaha Blue Blood Bulldog, Valley Bulldog, American Pit Bull Terrier,Staffordshire Bull Terrier, Bull Terrier, Bull Mastiff, or Banter Bulldogge. All they know for sure that they can differentiate between is French Bulldog and whatever falls under their category of “Bulldog” which even they don’t know.

To KOBE24MVP, I am by no means an idiot nor stupid and I only wish you allowed emails but apparently you spend your time not bothering to pay attention to what you read nor find out all the facts prior to incorrectly putting down on people. You seem to not have the nerve to get responses via email to your immature and ignorant comments you make!...that or you simply want to see how many people you can tick off. Either way, get a life and learn to pay attention when you read! And if you’ve got the nerve to start stuff with people have the nerve to leave an open line of communication so that you might allow someone to respond. Coward!


P.S. I'm aware that AKC does DNA testing. However, that's only for dogs that are AKC registered. My puppy is CKC due to his mother being registered through CKC (the father is AKC but all three dogs involved have to be AKC) so AKC can't help me. I grilled the breeder first, then spoke with my vet, then my next call was AKC. I'm in the process of contacting CKC for assistance so ya'll know. And by the way, my puppy is only 13 weeks old now and due to his looks (for all of you out there that focused on my not knowing what each breed looks like) for about 7 weeks now, I ask these questions.

Answer 1

The only way to confirm parentage and thus if the dog is purebred by a consistent pedigree of accurately recorded parentage in a multigenerational pedigree is to use a matching parentage DNA test. The dog AND it's parents (and grandparents, etc..) must be DNA tested and results compared to each subsequent generation of offspring. There are many, many labs who perform DNA parentage tested. AKC only contracts with a lab, they do not perform the actual test.



VetGEN, Healthgene, UC Davis Genetics lab, etc... all perform parentage testing.



The key is that the offspring DNA must be compared to that of the parents. If you wish to go further back, then also have each parent DNA tested against their own parents.



The test doesn't ID a breed, but does give you an idea if the breeder kept accurate records and thus increases the chances of a dog being purebred as represented.

Answer 2

I don't think there is a test for that. In fact I'm pretty sure that they don't test the DNA how you think they do.



There aren't any unique markers for specific breeds in the DNA. Basically, what they do is collect up a lot of DNA from dogs that are known to be a certain breed, then compare the DNA of unknown dogs to that library. In other words, there is never a specific gene or even a sequence of genes that will shout out that a dog must be this breed or that. It's more a matter of the DNA resembles this library more than that library. So the more closely related the breeds are, the harder it is to differentiate between the DNA libraries.



This is different from how they DNA test for certain diseases. In which case, we know what the markers in the DNA for certain diseases are and those will either show up or not. But breed testing, is not that straight forward. Maybe someday ...

Answer 3

Sorting through your rant to get to the actual question...





All dog breeds are too closely related for any DNA test to be accurate as to breed. They are accurate for parentage though. If you have concerns over your dog's parentage, then get a DNA test done. That at least will answer your question if indeed the sire is the real sire. If not, then you have bigger concerns that if your dog is purebred or not - the fact that the "breeder" scammed you.



Add: the legitimate CKC (i.e. CANADIAN KC) can help you. The crook-filled Con. KC cannot help you, so don;t waste your time and effort trying to get help from them. If indeed you did buy a Con. KC registered dog, then again, you got taken.

Answer 4

There is no test to scientifically prove if a dog is purebred or not. The test that claim to determine a dogs breed or mix are highly unreliable. (breed clubs have done test of sending sample from dogs with well known and proven pedigrees and the dog comes back as a mix of breeds that are breeds never even used when the breed was created hundreds of years earlier)



The only reliable K9 DNA testing is to determine if specific dogs are the parents of a dog,



Continental Kennel Club is used by breeders who have lost AKC registration privileges, are trying to register mixed breeds as purebred or are trying to get around AKC limited registration. So they aren't going to be much help.



As far as your dogs looks it is not uncommon for a dog to be poorly bred enough that it does not look like what the breed is suppose to look like. So your dog may be purebred just poorly bred. With the CKC it is also possilbe that the dam (mother) of your dog was of mixed breeding and registered as a purebred. It is possilbe for a mixed breed to look very much like a paritcular breed but they still carrie the genes of their mixed breeding and can pass them one to their offspring which could have also occured in your case.

Answer 5

There IS NO DNA test that will determine if a dog is purebred or not.



The AKC test simply determines parentage.

Answer 6

You're desperately trying to compare apples & oranges & it's IMPOSSIBLE.

Deny the facts all you want,they won't change. FACTS are facts.



The scam DNA is utterly useless.



The Bulldog is a real/recognized breed.

The French Bulldog is another,completely different, real breed.

The so-called "american" bulldog is a mutt,as are all the other mis-spelled lying-labeled mongrels w/"bulldog" stuck in their "names".



A "Con Krap Club" reg.(HA!) dog won't "look like" a real/quality animal because it's CRAP!

thanks for the answers EVERYONE <3
