This kit analyzes your dog's DNA and identifies the breeds in its ancestry. It provides scientific confirmation of the physical characteristics, behavioral tendencies, personality traits, and potential health risks your mixed-breed dog has inherited.

Thius kit sounds really awesome, and like it may actually prevent furutre health risks. Though, if you have a dog that is of an uncommon breed, I don't recommend it. The kit recognized 63 of the most common dog breeds, when there are hundreds. (via www.hammacher.com)
