Okay, so I went ahead and had a DNA test done on Cannon, by the lab that (a) has the largest gene database, and (b) uses a blood sample instead of a cheek swab.

Before I spill the beans, anyone care to make a guess as to what the report says?!?

Knowing how accurate those things are for breeds that haven't had their DNA mapped yet, I'd say Great Dane and Yorkshire Terrier ;)

But I also wouldn't be surprised to hear Black Mouth Cur if they have them on file. Almost all our dogs can be traced back to Wilkes, and Wilkes was notorious for crossing BMCs with Lacys. If they were out of a BMC gyp he called them Blue Black Mouths, if they were out of a Lacy gyp he called them Blue Lacys. And you can really see that influence in the bigger lines and reds with blue markings.

Well there was one word in your guess that is on the money!

Hmm, if it is one word, I'm guessing "terrier"... And though there may be many things in a Lacy, I don't think they have terrier in them. Though that would certainly explain their ungodly stubborn attitude :))

I know you and I have discussed this, but I'm not sure if people understand how a dog DNA test works. Essentially they look to match your dog's DNA with the known breed profiles. If your dog's breed isn't on file, but it is very similar to other breeds that have been studied, it may match up to the wrong breed. That's why so many of the tests show bizarre results.

It's also been proven they can't determine foundation stock in old breeds. Do you know how many generations it takes to get from 1858 to 2009? It's mind boggling to think of the number of breedings that went into our dogs.

So I don't think DNA tests can show us what the foundation breeds were. And because we don't have a profile yet, it would be hard to use them to prove whether or not an individual Lacy in purebred. But I'm still very interested in the results and hope we can work with other organizations to build a comprehensive database.

The cover letter states that the computer results were inconclusive, and so they did an analysis of his raw DNA to evaluate it against their possible 11 family tree models, and evaluated each chromosome against possible strong breed matches. What they ended up with is a 'significant' (50%+) correlation to the "Parson Russell Terrier", which is the AKC name for the Jack Russell Terrier.

It's possible to have a discussion with them, which might be interesting, but Julie you would probably be the best one to talk to them.

Very interesting. The fact that they are admitting that no, that can't clearly see a breed or mix, is a huge step. And mapping it against other breeds like that could have significant implications for tracking and uncovering genetic disorders.

I wonder if they would be willing to map a group of Lacys against each other. Now that Cannon is in the database, maybe they could run a sample from Sadie against that to see the correlation between them, and so on down the line. That would certainly provide more useful insights about Lacy genetics than haphazardly mapping their DNA against unrelated breeds.
