I'm getting a dna test done. Then what??

I agree. MARS dropped the ball on this.

This particular patent only applies to the technology of dog breed DNA analysis. I bet they have other patents that apply to this type of cancer research.

I checked MARS patents all the way back to 2004, and they didn't patent anything about DNA and genetic analysis. Most of their patents are about candies, manufacturing processes, pet foods, and healthy food additives.

Have you ever wondered and been in awe with how human conversation, can expand just like the rays of the sun. ONe idea leads to another idea or thought. And thinking we were going to Paris, we ended up in a wondrous round about way in Denmark?

Our world is a very fascinating place to live in. And yes sometimes dangerous, sometimes heart wrenching, sometimes heart warming.

Thanks Phil for all you contribute here, it is so very much appreciated by me, and many of us!

Thanks to everyone who asked questions, especially to Jen. If she had not posted about Minnie, we never would have had this conversation!

For sure and very true

A little more about the acceptability and accuracy of dog breed identification by DNA analysis from: Rethinking dog breed identification in veterinary practice

To avoid problems associated with breed misidentification, we recommend that veterinary practices adopt a single non–breed-based term to describe all dogs of unknown parentage, rather than attempting to identify the predominant breed on the basis of visual inspection. For new clients and for new dogs acquired by existing clients, we recommend including a short statement on the new client or new patient sheet expressing the hospital’s position. A statement such as the following could be adopted: Because new scientific evidence has called into question the accuracy of visual breed identification of dogs, our hospital has adopted a policy to not identify canine patients by predominant breed unless the dog is purebred, the predominant breed of the dog’s parents is known, or the dog’s lineage has been established through the use of DNA analysis. [Emphasis mine]

It has been suggested that DNA analysis correctly identifies the breed of between 86% and 99% of purebred dogs. However, between 2007 and 2012, the stated mean accuracy of DNA analysis of first-generation crossbred dogs of known parentage increased from 84% to 90%, and breed identification accuracy of DNA analysis is expected to continue to improve.

Wow this is hugely important! Especially for gathering stats of all sorts of important topics. Like dog bite statistics, like breed specific legislation!

Absolutely! That's why it's important that the accuracy of DNA dog breed testing keep on improving. It looks like veterinarians are going to rely more and more on DNA testing for dog breed identification of their patients, too.

Absolutely fascinating study, and so very vital to recording accurate statistics on a variety of dog related issues from detecting breed related conditions to tracking dog bites, etc.

Has DNA testing of specific purebred dogs* reached the point where a blind DNA sample could be sent of a purebred dog and the DNA results determine the breed accurately? It seems to my unscientific mind that this would be the ultimate test to prove the accuracy of the DNA testing.

*Defining a purebred dog as one that is registered with a reputable registry and has a minimum of a 5 to 7 year pedigree.

What say you all to a Science Forum? Where we could encapsulate in some orderly fashion a whole host of research, fascinating discussions, and get to broaden our horizons?

Hint 1: It is not MARS Labs.

Hint 2: It is not a pharmaceutical company.

Still don't know?

Answer: It is researchers at a federally funded research institution, Fred Hutchinson Cancer Research Center - Wikipedia, the free encyclopedia See link to the patent below:

Ummm...feels 'off' a bit to me...

I do have a question - and this isn't meant to stir the pot or change the direction of this thread.

If I am reading correctly the results of Minnie's DNA test is entirely a result of the Mars testing in which they compared the DNA samples of 10,000 dogs to Minnie's sample. I know 10,000 is a big number, but is it really when we consider all of the different dog breeds and mixes and DNA combinations possible?

Also, how many Yorkies were DNA'd to come up with the Yorkie DNA identification analysis -- and how were the Yorkies samples that were tested proven to be 100% Yorkie?

Knowing that Mars is a "for profit" company I am a bit hesitant to take the results at face value. I know I know, I'm a bit suspicious, just like I am of the dog food comparisons that are "owned by the dog food company that comes out on top.

Some time back there was a long thread about Mars testing in a Beiwer vs Parti Yorkie vs Yorkie discussion. That one got rather heated and I certainly don't want to visit that again, but after reading through that long thread and reading some of the Mars site, I kinda doubted the validity of the testing. Anywho, with that thread we didn't have a genetic expert on board to help explain all the ins and outs.

Oki, I'm done - I hope I didn't offend, I'm not even trying to be a devil's advocate and look at the flip side, I honestly want to know when and how to believe test result.

I missed that thread...will have to take a look.

The European ones were certified by the European clubs.

I think that the quality of dogs in their database is good, but they really need to add more Yorkie DNA samples to their database.

MARS is a family owned business...with an "unknown" $$$$ factor since no shareholders to have to report to...to the best of my knowledge...bit it was interesting research...

...or similar.
