I get really irritated at people who say "I cant stand Dobes/Rotts/Pitts because they are mean" Get a friggin clue would ya? I have a Dobe, and he is the most loveable mutt in the world. My brother has a Pitt, and I have never heard him so much as growl, and the same goes for my friend and his Rott. (A toy Chihuahua is trainable to be mean). Before you say that you don't like them, take the time to meet the "Viscous" dogs and see what sweethearts they can really be.
