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.
