Especially when you know better and your just trying to fool mars testing

I meant to thank PStinard last night but got involved in something else that needed swift attention. I agree, helping us laypeople to understand issues like this one...PRICELESS!

I find it ironic that no comments are allowed to be seen by other users on your Blog here joyziegirl/Marlene/utob. I also think it's kind of shady that you tried to include someone else on your sinking ship by quoting part of a conversation & making it appear they support you. I don't think anyone here supports what you're doing (breeding Merle to Merle).

Coat color DNA testing in dogs: Theory meets practice

This article is behind a pay firewall, but it describes commercial DNA testing for coat color genes in dogs and has a table of alleles that have been tested for in various breeds, including the Yorkshire Terrier. Yorkies have been tested for the presence of "sp" (Parti color), "b" (brown), and "e" ("Gold Dust") alleles. The only problem is that these alleles have very specific DNA fingerprints, and they arose in other breeds. They could not have arisen spontaneously in the Yorkshire Terrier.

Is the table the same or significantly changed from the table shown in the article I posted from 2002? Just curious how much has changed in the dog breeding world according to the experts since then.

I will use layman terms because I am not a breeder nor geneticist. You are breeding HYBRID, DESIGNER DOGS and making money off their backs, you are by far an accomplished creator, nature did not intend for you to play mad scientist...you must be so envious of the breeders who work so hard to breed to standard and all their hardwork...you throw two dogs together and call them Teacup, miniature, Hybrid, etc...what the hell is that? You play people for fools and market toward innocent people with little knowledge and your dogs are nothing more products of two common mutts...I've seen many of your dogs, Michale, Monet, Mona Lisa, Mork, Mindy and quite frankly they don't look like the best representations of their breeds, and I don't mean this as a slam against them (I'd rather offend you then your dogs so please don't read this to them)...wait they are not even a breed...they are mutts, this is according to your logic, by the way.

You are the kind of breeder that produces many of these dogs in shelters and rescues...Your breeding program is pathetic and I detest breeders such as yourself. Do your pups a favor, release them from your laboratory of creation and get them good homes, be done with this, where on earth is your conscience?

Geesh, I been busy doing laundry, I come back and Marlene is suspended...strange how the truth (and I'm guessing) brings out the ugly in people...no matter, at the end of the day I am here to educate and inform and hopefully, god willing...I can save one person from crying over a sick or dying...dead pups...its so horrible what these byb's are doing...I know this first hand as do many of us, sadly...very sadly....

Hi, this article is about coat color DNA testing. The table shows what coat coat color genes Yorkshire Terriers have been tested for, and what the results were. If you PM me your email address, I can email you the PDF of the full article.

Pstinard: research what the solution was for the rampant hyperuricosuria defect in Dalmations.

I should not post, as my memory is a little vague on the details. But the breeders were asleep at the switch as it were, and finally had no viable breeding dogs to breed as this dominant gene was rampant throughout the breeding world of Dalmations.

Now one very brave breeder did something about this. How-ever his motives were to save this lovely breed, and did it very knowingly and with knowledge. He did have to outcross, and then spent a long time, breeding back into purebred Dalmations without this very un-healthy gene.

What this person is doing, is not of the same ilk, in my mind.

Are you referring to the time AKC sent the Dalmatian back to the FSS program? I know someone that worked on that project. I just sent them an email. I just got a text that she is traveling but will call me later this evening. That was very serious and took about 5 years to correct. If they are the same there has to be something published with AKC or with the Dalmatian parent club.

Hi, I'll park some links here so people can read up on this. If any of these are behind firewalls, I'll quote the relevant parts later. Cross breeding might be fine for a breed of dog in which ALL individuals are affected by a genetic disease, but there are still plenty of healthy breed standard Yorkshire Terriers. The people doing cross breeding with Yorkies are doing so in order to breed in "lovely" coat colors.

From what I gathered in a quick glance at the Dalmation Heritage Project, a Dalmation was crossed to a healthy Pointer, and then backcrossed to purebred Dalmations for 10 generations, selecting the healthy Dalmations each generation. They are still maintaining the gene in the heterozygous (carrier) state, because they are afraid that with such a low amount of diversity from doing this kind of breeding, the gene pool would be too small if they started creating homozygous healthy Dalmations.

Now, if they're being this careful and ethical with Dalmations, imagine how unethical the breeders are who are crossing other breeds to Yorkies for only three generations and then creating homozygous chocolate, parti, or gold dust Yorkies.

I forgot to mention that the hyperuricosuria defect in Dalmations is recessive, not dominant.

Thanks Phil. And that man was granted recognition for his improved dalmation breed in 1981.

Great I wanted other folks to see that National Breed Clubs can work very well towards the betterment of the breed. In fact it is one of the very important things they can do.

Another example of a breed club, trying to do the "right" thing is the Havanese Club. Take a look at all the health tests the National Club recommends.

They quite clearly don't want to run into some of the problems that other toy breeds have, LS, LP, Deafness, thyroid etc.

Does anyone know why my Mia(1) was deaf? She was a Biewer, verrrrryyyy pink skin, spotted like a dalmation (not insinuating she has any dalmation)....just curious what would cause this?

Phil Mia died early this year from heart condition, she was 1 years old. (She was a very very special girl, she was Lynzy in a dogs body)!!!
