I love my pitty he has been the smartest dog I have ever owned and I read somewhere that people actually use labs to fight has anyone else heard that? so there is proof that even a lab can be a aggressive dog if you train it to be. All my pitbull does it give you lots of licks and is very animated he is funny as hell. We keep are pit indoors and I think that helps alot because he gets the attention that he needs I think a pitbull that sits outside and never gets attention is going to be aggressive because it does not get any love. Pitbulls are great company and they want you to show that in return and give them attention.
