Bests & Worsts Reviews from Amazon

The Shelter where my dog was adopted called her a "German Shepherd Mix" and the 3 Different Veterinarians she's been to, all said she was a "German Shepherd Mix", however; the results didn't even show ANY percentage of German Shepherd at all. Yet, showed 20% Chihuahua and 14% Dalmation. Those were number 2 and 3 of the highest percentage, with 24% Lab as number 1. We did send a photo in and there's no doubt at all, she has Lab in her. I don't know, I'm not a Specialist, but this test just doesn't seem accurate in my honest opinion.
