This story about the accuracy of canine genetic testing came to my attention the other day. http://www.vin.com/Members/CMS/Misc/VINNews/Default.aspx?fromfrontpage=1&id=23206&
It gives some ideas about which are the best genetics tests to use. It also has a section of 5 dogs, what breeds they actually are and what breeds the test said they are.
I’m not sure that I see a real medical benefit in these tests. The companies say that, with breed knowledge, we can anticipate what sorts of diseases a mixed breed dog might get. Well, maybe. One of the strengths of being a mixed breed is what is called hybrid vigor. That means that a poor genetic trait in one breed may be diluted out by another breed.
I do think that these tests are kind of fun. I’m not sure they’re worth the money, though. The blood sample version is about $80, the cheek swab version is about $55. We had some clients who got one as a Christmas present. I thought that was pretty fun.
I would say that if you’re curious about what the test says and don’t mind spending $50-80, then go for it. But if it’s going to break the bank, save your money for heartworm medicine.
