that's a load of crap. i didn't buy a rottie based on my personality. and no one that i know has ever bought a dog based on personality. only the ignorant shit heads do that sort of thing. mine was a rescue, she was abused by her first owners and due to that has lost a leg. i took her in because she is one of the sweetest dogs i have ever seen. when she was younger she would wrestle around with me and if she accidentally got me with her teeth she would jump up on the couch witha very pitiful "i'm really sorry" look on her face.
