I haven't by any stretch read all the posts here. Is OP going to post the test and everyone is just waiting to see it?

I just took a look at my test for Momoko. When I adopted her, I was told that she she was an F1 Morkie. However, when I had the test done, I didn't specify between the purebred/mixed breed/designer dog. I just wanted to see what results would come back. Anyway, here's a link to Momo's test...it will give you a vague idea of how Mars interprets the data:

The short answer is yes. Jen still has questions about the results and what they mean, and she's trying to figure out the best way to go about getting answers. I gave Jen the contact info for customer service at MARS Labs, and also offered the expertise of all of us Yorkietalkers.

Good. I'd be very interested to see one of these. I doubt I'd ever need something like this but it's good to know about it and what it will/won't do.

Wow, MARS went above and beyond the call of duty and gave you a free Designer Dog analysis! :thumbup::thumbup::thumbup: The Principle Component Analysis (PCA) is the heart of the analysis. That's the two pages of graphs with the clusters of dots, each one color coded to represent a particular breed of dog, or the F1 (first generation) cross between a Maltese and Yorkie (Morkie). Momo falls exactly in the center of the cluster for the Morkies in both analyses. They left out the graph of the homozygosity profile for Momo, but gave a verbal description of the results--that Momo has the expected homozygosity/heterozygosity of an F1 Morkie, in other words, that Momo is the result of a cross between a Maltese and a Yorkie, and not the result of a cross between two Morkies. Now I REALLY want to see the results for Minnie, because I'm thinking that maybe they did a free test of breed purity on her DNA once they realized she only had Yorkie DNA in her.

Check out Momo's report that Teresiana posted! For a geneticist, it's like uncorking a bottle of fine wine. (Sorry, I just can't help myself ;).) I'm hoping to see something similar for Minnie, but as a purebred Yorkie, of course. Can't wait to see Minnie's report!

Drum roll please... (Minnie's test results, part 1)
 

Jen emailed me the link to Minnie's test results and asked me to post them with personally identifiable information (full name and address, etc.) removed, and here are the first 4 pages. The last two pages will follow in a separate post. Because the only breed detected in Minnie's DNA was Yorkshire Terrier, they did a FREE purebred test (thanks MARS!). Minnie does indeed test as a purebred Yorkshire Terrier. That said, she does fall on the edges of the Yorkie group in the PCA analysis (the two pages that will be in my next post). In other words, Minnie doesn't fall in the middle of the group of typical Yorkies, but doesn't fall completely outside the group either. I'm sure that the other Yorkies in the MARS database conform reasonably well to breed standards (I sent an email to MARS asking how they chose the Yorkies they use as a DNA standard in their database, but they haven't replied yet). My conclusion is that Minnie's unusual appearance is due to a few single gene mutations that were either carried by her parents (most likely), or arose spontaneously (less likely, but still possible). If anyone has questions, please ask! Jen, I recommend that you send an email to the MARS Lab's customer service along with a photo of Minnie and ask for their explanation of Minnie's appearance as well.

Drum roll please... (Minnie's test results, part 2)
 

Here are the last two pages of Minnie's DNA test report. These are the heart of the purebred test, the PCA analysis, which I described in my last post. There is a lot of meat in these graphs, so if anyone has questions about what they mean, please ask!

Oh, I forgot to mention the homozygosity test. This is a test of how inbred Minnie is. Minnie is more inbred than the average Yorkie in their DNA database, but isn't in the abnormal range (tail of the curve), either.

This site seems to want to download this test. Is it supposed to download to to my computer - not just be there to look at?

There is something incredibly attractive about this statement, I love your enthusiasm for geneticism! lol!!!

For me, I could view the report on the website without downloading it. My browser on my PC has a PDF file viewer that allows me to do that. If your browser doesn't have a PDF viewer, you might have to download it in order to view it. I don't know what you need to be able to view it on a smart phone--I seem to remember that it's more difficult...

Thanks! :) It's my profession, but it's also my hobby. It's great when something can be both!

Ok I read the results and while I'm no geneticist, I can see that she is in the lowest range, but I still just can't see Minnie as a Yorkie, how sad that the breed is being so over bred that we can't even decipher the Yorkie from the Yorkie anymore.

Minnie is beautiful, don't get me wrong, she really is gorgeous, I would have loved to have a pup that looks like her she is so unique...at the end of the day the final analysis yields that Minnie is a Yorkie, the breeder did not lie, but the breeder did knowingly sell a very obvious poor representation of the Yorkie Standard, not sure there is any recourse here.

What say you Pstinard?

I had to read this post, not all of it but enough to know the concern about the yorkie not being a yorkie. I'm totally in shock that the DNA came back saying it was indeed a yorkie.
I do breed yorkies and have DNA done on them. I do this for the buyer.
I know there are a lot of "yorkies" that sure don't look like pure breds...and the so called designer dogs..really!
Most all dogs are cute, but you should get what you paid for..
I don't remember if this yorkie is AKC registered but I would NEVER buy one that wasn't..that is a big red flag.

According to the figure captions for the PCA analysis, Minnie was compared with Yorkshire Terriers (US Show) and Yorkshire Terriers (UK Show). To me, that means that MARS used only DNA from show dogs in their comparisons with Minnie's DNA. It's interesting that the US Show dogs clustered more closely together, and that the UK Show dogs were more spread out (showed more diversity). (Sorry that doesn't answer your question, but it's something I just noticed, so I had to throw it out there.)

Back to the question... Yes, Minnie is a Yorkie, but the breeder did knowingly sell a poor representation of the Yorkie standard. (Wait for the hair to grow longer?!?!??? Give me a break!!!) I think that if this ever went to court, Cristina (Minnie's breeder) could argue that at least Minnie is genetically a Yorkie. If push came to shove, a parentage test could be ordered to determine whether Minnie is the offspring of the reported parents, but I'm guessing that the results of such a test would favor the breeder :(. Minnie is the result of a breeder who didn't know what she was doing, but at this point, I don't think there is much that Jen can do about it. Cristina has other ads on ebay, but it looks like her dog breeding is more of a sideline than a profession--I don't know whether her litters and breeding program are registered with the AKC. If I were Jen, I'd file a complaint with the AKC. I don't know what else she can do at this point other than love Minnie as a very special and unique dog.

If she has demodex it can explain the hairloss. She's beautiful regardless, I have a chihuahua with demodex just need to take extra care. If you keep up with her treatment she should look like all other dogs!

Even if she is purebred which I doubt the breeder NEEDS to give you some compensation. Demodex mange is transferred from mom to offspring so ALL her brothers and sisters have it. I think you need to get on her case! I did it with my chihuahua and the breeder gave me back half the money which was $250 my chihuahua was going bald and I spent way more on vet bills! Truly ridiculous I don't think there should be any breeders besides show breeders!!

Good point about the demodex! We were so caught up in the DNA aspect that we almost forgot--Jen does have a case for getting some money back due to Minnie's health issues. I hope Cristina (Minnie's breeder) does the right thing...

I agree!! Thankfully my breeder was sweet but I will fight it because my poor baby has bald spots and that's now what you paid for!

IF Jen can find out if her state has the puppy lemon laws, she CAN get ALL moneys she has put out on vet bills from the mange, back from the breeder. Any GOOD breeder would have already offered to pay those bills AND at the very least a partial refund for the purchase of the pup. What this breeder does now WILL tell IF her intentions are HONORABLE or not;) AND when anyone Googles this breeder from here on out YT & this thread WILL pop up for ALL to see, so it would be in the breeders best interest to do rite by Jen;)

Just needed to add this. Even if her state has no puppy lemon laws, I am certain that Jen would win in court , her money for vet bills for the treatment of the mange.

Who is the breeder? I only know her by baboon or Christina.

It has not been said, you may need to PM Jen for this info. IF I were Jen & going through this I WOULD Deff post that info to protect any future buyers. It Will come out before it's over with.

Financially this isn't cheap because she's been there prolly 4 times for this condition already. I'm taking her back again today because there prolly going to add something else to it and add another round of treatments. They may end up having to shave her and do a cream who knows. But she's my baby and ill do whatever it takes to make her better. She didnt ask for this but she has it and as her mommy it's my job to make sure thst happens :) I would appreciate it if the breeder would have offered something but can I make her ?? Who knows i don't know enough details yet but well c.

The certificate was printed sideways, and I wanted to make sure all of you could read what it says.

The first important point is that the test is not designed as a purebred test. Second point is they are only talking about the last 3 generations, and for most dog enthusiasts, this is way too limited.

As I stated earlier, this test measures against previous results. It’s considered one of the weakest forms of testing there is, however as they get a get a wider base, closer to 100 thousand or a million, the results will be much more dependable. With only 10,000 dogs in the sample, the results just aren’t that accurate in my opinion, since the genetic code of dogs is just so varied.

PA does have a puppy lemon law:

Consumers: Protecting Consumers - Pennsylvania Office of Attorney General

See item #3:

To preserve your rights under the Law, you must take your newly purchased dog to a licensed veterinarian for examination within 10 days of purchase. If a veterinarian determines, within 10 days of purchase, that your dog is clinically ill or has died from an injury sustained or illness likely to have been contracted on or before the date of sale and delivery, you have the following options:
(a) Return the dog for a complete refund; (b) Return the dog for a replacement dog of equal value; OR (c) Retain the dog and receive reimbursement for reasonable veterinary fees, not exceeding the purchase price.These options do not apply where a seller, who has provided a health certificate issued by a veterinarian, discloses in writing at the time of sale the health problem for which the buyer later seeks to return the dog.

This law is similar to Florida, my advice would be to talk to the breeder yourself and try to resolve this. Believe it or not the court has better things to worry about and if she has a good lawyer which most do, they will find a crack. I would attempt to settle this calmly,I usually have my husband talk for me in cases like this to be like the mediator. If that doesn't work have an attorney write a letter, you need resolution and Im sure like most of us you have spent a lot of money in the purchase of your yorkie. In my area they are not below $1500 and although you love your puppy, she makes money and she needs to realize she's made a mistake. Im sure she looked DIFFRENT and Im sure the siblings have the same problem as you. Im empathize with you deeply!

As much as the breeder says she loves her dogs I do believe her but in the same matter she is completly aware of the situation I'm in w Minnie with my concerns w her apparence and skin condition and and didnt act concerned about her apparence. or mention n e thing bout money to me. She said its cuz of her skin condition butbits not that cuz before her skin condition arrived her look was off. Her look was off at time of getting her. Did she really not think it was? I'm def not that type of person to ask for help but I am the type to expect to much out of people I guess :(

If Jen's breeder is just a person breeding her personal pets, and sells them directly to the public , and she's not a license business, none of those puppy laws apply to her. No law suit well hold up in court, Talk to the USDA, and your states Department of Consumer Affairs. Buying a puppy out of someone's house,..... same thing as buying something from their garage sale. Buyer Beware!
