Yep, Labs...the number ONE most popular dog in America...we've pretty much destroyed them. I see a lot of idiot labs, with really lousy conformation, no brains, etc. Just got too popular. Two breeds of note that are terrific "watch dogs" or "home defense" dogs---Cheaspeake Bay Retriever and Bouviar des Flandres. Do not argue with either. They are both sensible, great family dogs, that will die for you.
