actually pit bulls were never bred to be aggressive towards humans, ever. and I disagree with you yuckaduck, I think ALL dogs should be fenced in and controlled at ALL times no matter what the breed. and I think there should be regulations, a test everyone has to take before being allowed to have a dog. if your scores says you are not allowed to have the most high drive, dominant, aggressive, dangerous hard headed breeds then you cannot even get a chihuahua. should have to qualify to have the most dangerous before you can have the least dangerous. be able to take the test as often as the drivers license test so if you fail you can go learn more. test should also be worded differently for every person.
untill we can trust the feds enough to allow such regulations, no dog should be banned and no dog should be required to wear anything other than a leash. if a dog bites someone, they lose the dog, get a huge fine (not a set fine, but say 10% of their annual income) and a month in prison, or atleast house arrest with the little anklet on. and after that if they are ever found in ownership of a dog, or in physical control of a dog, or a friend or family member brings a dog to visit them they get a new fine of: home owner loses their house. non home owner loses 50% of annual income for that year in a fine.
sure, maybe the fines and punishments are too high, feel free to lower them but they should be high enough that people would fear them, and that people wouldnt just think "oh a $100 fine and I lose my dog? no biggy I'll pay the fine and buy a new dog cause I make more than $100 every time the dog fights." and it should apply to EVERYONE and EVERY BREED. heck, throw cats in there. cat bites or scratches someone other than a break in, fire rescue, or vet visit you get the same punishment.
