Do Yorkies sometimes look like Chuahuas?

That's was my point, I guess, if it's not a mix it will show only Yorkie right?

What kind of testing does the AKC do? Is it basically the same as the MARS test?

AKC does dna testing to determine parentage only. Samples are collected from the sire/dam and the puppies.

Wow, it only tells who the parents are? What if one of the parents aren't purebred? I can see it working in Show dogs but what about the other dogs....

The AKC only registers purebred dogs. DNA testing requirements ensure that an AKC puppy is purebred. None of the "alternative" registries require DNA testing which is why there is no guarantee that you are getting a purebred if she has papers from any registry other than the AKC.

Many of the alternative registries only require a couple of photographs and the signatures of two witnesses to register a dog as purebred with them. The witnesses don't have to be veterinarians or experts, either. Your Uncle Fred or the neighbor down the street will do just fine.

I recall a few years back that some scientist supposedly researched the DNA of dogs and wolves and found that dogs were truely decended from wolves. However, I am thinking that I also read some where that DNA results in dogs get really hard to determine which breed the origional breeding pair belong to if they are 3 generations from the origional parents and mixed.

So how does the scientist determine that dogs are from wolves if the parentage gets murky so fast ? Makes me wonder about some of the scientific findngs. Oh and on Rachel Ray one day, they had people DNA'ing thier dogs and the one that made me laugh at the results and not belive those, had an ancestry of all short hair dogs breeds, so why did the dog have medium to long hair..... HA on DNA results from whatever company it came from!

[Abby08]

I think that the DNA only works if the folks who use it are honest. Most of the local folks say they have DNA'd the father, so that they know if someone brings back a puppy and it is not from their dog then they have proof. I honestly don't think it garantees the purbred dog is purbred. J MHO

I read through the FAQs at the MARS Wisdom Panel Mixed Breed Analysis site Frequently Asked Questions about Mars Veterinary and read the questions concerning if it could test for purebred dogs. The answers confused the heck out of me. I do not understand how a test that can identify all sorts of AKC breed identifiers in a mixed breed could not also show that a dog only has the one AKC breed identifier and show that it is a purebreed. If what I am reading is right, then even armed with the test results, the OP may still have no proof to offer against the seller. Color me

Since the test is designed to be used for determining the heritage of mixed breed dogs, I doubt if the results would carry any weight legally. To date, there isn't a test to prove if a dog is purebred or not.

Whether Ksena is a purebred Yorkie way off standard or a mix, it really doesn't matter as it won't change her appearance. Since the OP saw in in person before she purchased her, I doubt she has any recourse except returning her to the breeder.

Puppies from backyard breeders and pet shops/puppy mills usually grow up to be pretty far from the breed standard.

Abbey08, I have wondered about that too, and I would be interested to read anything that explained it in layman terms. I sort of know about other ways that DNA can be tracked - for instance, dogs and wolves might have the same type of mitochondria. I believe that these are always passed from the mother in primates (and all other species??), and that's where a lot of information about humanity's origin comes from.

Sometimes I see on Animal Planet that ridge backs are supposedly descended from some type of African wild dog type, or that chihuahuas are from foxes, but that makes no sense to me, since all dogs can breed, meaning that there must be one source species.

It is pretty amazing to look at Thor, a 4 pound yorkie with silver hair, and imagine that his genes came from wolves. Says a lot about the diversity of the genome!

Well since i was having the same concern as you with Arizona, I called them to ask them all these questions.

1. It states on the site that it does not determine breed only parentage. Sooo then....

2. I asked them what happens if it is determined that only one of the parents is the pups they said:

They would contact the breeder and ask them if there is another dog that mothered/ fathered the pup.......and if not then they would begin open an investigation on the breeder.

Also my pup would be placed on a limited registration until the lineage is determined and that sometimes it could be three or four years down the the road but that eventually the it MAY be found.

AND that was it!

In the world of DNA knowledge, it's like we have discovered the molecule, but we have yet to discover the atom.

You are talking about a different type of DNA test, the one the AKC requires for frequently used sires to prove parenthood.

The MARS Wisdom Panel is the one we are discussing in this thread. It tells you the different breeds in the DNA of a mixed breed dog.

It's confusing, isn't it?

I'm thinking the opposite to be true....Anyway, Ksena chased a big poor quality golden lab or a lab mix ( ) off her turf the other day...I started to think she may be part Pit Bull......

I looked up characteristics of chihuahuas and Yorkies to try to further analyse myself because it is driving me nuts and it said Chihuahuas can jump almost as high as cats....Ksena can almost get on the couch...Poor Jonah's feet barely leave the floor.....Also, while I'm on here anyway, a girl who lives beside me came by with her part Chi/Yorkie to see the pups and her dog and Ksena were going nuts after each other...very funny...Jonah's like huh???? Does anyone have a crazy pure Yorkie...I know chihuahuas go off but didn't realize Yorkies did too??????????

LOL I have a purebreed 6 month old yorkie who can get out of a 30 inch high xpen if i dont put the top on it, and he has been able to jump on the sofa since he was 3 months old. He weighs 2lbs 14 oz . I think he is part kangaroo

I should have clarified.....I was talking about the AKC because my dog Arizona is AKC registered and I was having the same question about whether she was actually a Yorkie. She just doesnt have the same "look" to her. I had rebeccag look at her and we both agreed about how she looked a little chihuahua-ish.....and I had called AKC about this and that was the conclusion. So technically...what im saying is that I think a dog could actually be AKC registered and not purebred. Im sorry is this is confusing....but your right its all confusing.
