The most fascinating part of this to me is that roughly 88% of mixed breed dogs passed the test. So if you're just looking for a great dog, a mixed breed might actually have a better chance than a purebred!
Unless you're getting a lab. I've never met a lab that wasn't the bestest doggo ever lol
Without knowing what types of mixes were in the sample I wouldn't draw too many conclusions. Poodle and lab mixes are some of the most popular mixed-breed dogs.
You know that checks out, I always have to get purebreds because of allergies, and the ""Better"" the breeding was, the more high-strung they would be.
