I have a german shepard newfoundland mix. One smart mother fucker, damn smartest dog I have ever seen. He knows hand signals, multiple commands for sit including plant your ass, lol. I can walk him in traffic with out a leash, tell him to go to bed and he will go upstairs to my room and lay down. Very well mannered to, shit he is the perfect dog....huge and nice, think he takes after me pretty well................hmm, did that sound right. Yeah I guess so as long as I don't take after him it is okay.
