I want to know every ones opinion on this subject, because there always seems to be different point of views and I'd like to know what the facts are if there is any. When I ask neutral knowledgable people in the subject of dogs about what breed is nick named the "Nanny dog" I usually get 1st The Newfoundland 2nd SBT and 3d APBT as answers. I looked it up from wiki to dogbreed info.. I feel this might be pretty accurate, but at the same time I feel there almost isn't a right or wrong answer to this question, not sure if the SBT or The Newfoundland was given this nick name first. What do you guys think? Or how do you guys feel about the subject?
