DNA Testing for Havanese Anyone???

I wonder if my Shadow isn't part at times. Has anyone done this on their Havanese? If so, which one and what did it tell you?

If you have a registered Havanese, why would you bother?

He's registered but I wondered exactly what information they give. Someone I know did DNA testing for their dog that gave the genetic predispositions for diseases/cancer based on the dog's DNA. They were vague on the details but it sparked my curiosity. Curious what it would say about the breed...if it would say 100% Havanese or something else?

I don't know if it has improved, but in the beginning, they didn't... not because the Havanese tested were NOT purebred Havanese, but because the testing companies didn't have enough Havanese samples in their database for comparison. So they came back with some WILD combinations as computers tried to match things up. The fact is that ALL dog breeds share an awful lot of DNA.

If you want to know about specific diseases, you'd be better off working with your breeder, to test for the specific diseases that we KNOW we can test for in Havanese. (and there are a few) I believe most of these are done by UC Davis, though Thyroid, which, IMO, is one of the most important ones, is not a DNA test, but a blood test, and is done by Hemopet. Others can be done locally, including eyes and heart by a board certified local practitioner, and BAER testing for unilateral deafness, if it wasn't done by the breeder already when he was a puppy. That usually, but not always, has to be done at a university hospital. Patellas can be checked by your local vet. Hips and elbows require xrays, sometimes with sedation.

But, the question is, Why? Unless your dog has the symptoms of some disease, or you are intending to breed him, it would cost you a lot of money to do all this, and you'd just be borrowing trouble. Even the (simple for the dog) DNA test, if it came back positive for a predisposition for some disease wouldn't mean he'd necessarily GET it... it would only mean he was more likely to get it than the general population. So you'd have that hovering over your head to worry about all the time.

I can see doing this if you have a mixed breed and you have no idea what genetics are behind him. But in the case of a purebred Havanese, we already know what diseases are more likely, (not many, as we have a relatively healthy breed) and can keep those in mind as our dogs get older.

yeah save your money. , the human ancestry companies are not accurate and I think the dog ones even less.

My gut tells me it is a waste of money. Yet I still wondered if any Havanese owners have done it. I "think" we'd all get the same results.
The person I know that did it had a mixed breed dog. She did the Embark

One of the tests supposedly gives DNA matches. If true, that could be fun since our havs should all be related. For example, our Nickie and Louis are (on paper) 1/2 2nd cousins 3 times removed to Kodi - fairly distant. Genealogy and DNA addict here, but we haven't tested the havs.

We probably have members on here with dogs that are related and they don't even realize it. I would love to meet the other Havs from Shadow's litter!

I had Bingo (a mixed breed) DNA tested with the highest level Embark kit. the breed breakdown was fairly accurate as far as we knew about his parents. They test for 165 different health related conditions, all of which he is clear of, plus they keep his sample on file so whenever a new test becomes available, he will be tested for it at no extra charge. They specifically pointed out the breed specific conditions for his mix.
My feeling is that if he were genetically predisposed to a condition, it could be one that I could take steps to avoid becoming a reality, through diet, supplements and careful observation.
Some other interesting aspects of the test are gene dominant/recessive breakdowns for coat textures and colours (Im sure these are more predictable in a purebred), and other body features like hind declaws, size, eye colour etc. All of these were accurate.

I did the test for fun, but I did learn a lot of interesting information from it.
