Good article with very interesting information. Personally, I prefer mutts. I have 2 street dogs and they never had a health problem. When I had "purebreeds" (I had a poddle, a basset hound, a cocker spaniel and a boxer in different stages of my life) they all ended ill and die younger than mutts. My dogs live perfectly in armony with my cat and are much less grumpy than my basset and my cocker. ¡Go, Mutts, go!
