While I personally am not a fan of pits or any of the "attack" or "guard" type dogs due to the fact that historically they have attacked people and are strong enough to kill and maim, it is the owners fault in the end for allowing such behavior to take place and I do agree that breeding is also the problem. The main problem I have with pits in my area is that the type of people here who own them are the sort of people who have them because they believe it is cool to have a big mean pit bull, if they don't own pits they have rotts, let them roam and breed out of control then give away or sell the pups without regard of which parents they came from, responsible breeding would definitely help the reputation of these breeds of dog. Also no matter the breed, more than one dog roaming forms a pack metality, this is when roaming dogs cause the most problems. A 14 month old child was just killed and the mother attacked by 2 pits down near Milwaukee a couple weeks ago. Another example of irresponsible people. I do feel they are a dangerous breed due to their pure muscle and they need to be kept accordingly, I don't buy into "most do bites are by small dogs", that may be true but most dog deaths and severe attacks aren't from toy poodles and other nippy little ankle biters.
