Who said anything about what kind of dog was smarter? Talk about Pandora's box...
I've been privy to 3 great dogs in my life: AKC Doberman, AKC Chocolate Lab and the dog that rivals them both, was by best guess, 1/2 Rottweiler, 1/4 Lab and a 1/4 German Shepard. I'm not questioning whether purebreds or mutts are smarter because that is determined on a dog-by-dog basis. The debate is about standards and the adherence to, or not, of the breed standard. I will agree with you that a driver to the breed standard is $. After all, $ is the root of all evil right?!?
