Sorry Hal, but you are wrong. Ive done plenty of research on this and have this argument frequently. Usually it is with people such as yourself that let their emotions and personal relationships get in the way reality. Similar to the way Obama got elected.

Heres the breakdown of Pit Bulls VS the second most aggressive:
1. Pit Bull
Varieties included: Pit Bull, Staffordshire Bull Terrier, American StaffordshireTerrier
Registered dogs (U.S.): 2,683
Child victims: 661
Adult victims: 519
Maimings: 819
Deaths: 159
2. Chow Chow
Registered dogs (U.S.): 1,592
Child victims: 35
Adult victims: 14
Maimings: 34
Deaths: 7
Theres 18x more attacks on Children, 37x more on Adults, and accounts for more than 22x more deaths.
I could keep going, but wont. Problem is when emotions are involved, facts dont matter. Im not saying one day YOUR dog will snap and kill one of your children or you, but I am saying that by owning a pitt bull you up your chances by 20-30 times and that can not be argued.
