I have to step in and say something. I have had pits american bulldogs etc. ALL were big possibly aggressive dogs, and I will also say these breeds do have the POTENTIAL to become more aggressive due to the OWNER. Pits have gotten a very bad rap for 1 because of stupid ass owners and 2 their popularity. They are probably one of the most, if not the most popular breed or mixed breed. My 115 lb american bulldog "tried" me one day by turning and growling at me and I wooped his ass and now dominance has been established, thats how the dog world works. I dont care if its a Chihuahua or a cane corso, it doesnt matter. I have seen way more little piss ant dogs that will nip and bite the shit out of your legs/pants than I have seen pits "attack", but you never hear of these stories because no real damage was done. The dogs feed off of their owners alot of times. For example, when we are walking my dog, if my wife shows that she is ok with a stranger walking by, then he is ok. If she shows concern, he is on high alert and most times will go ape shit barking at that person. I dont believe for a second that pit bulls should be banned, the owners who dont know how to train their dogs are the ones who should be banned. And that goes for all breeds. YES there are some "bad" pits out there, just like there are some bad labs, bad rots, bad EVERYTHING!!! It all comes down to the owner for the most part. PERIOD
