I was born and raised in Miami-Dade County, Florida. They have had BSL there since 1990. I can tell you, it does NOT work.
What people expected out of the ban: We ban these dogs, they'll die off and be put down, then we'll have no more 'pit bull' or severe dog attacks.
What actually happened: Some dogs were taken, put down, and died off. There was more or less a 'black market' for APBTs. Bad owners hid their dogs so they could use and abuse them like they had been already. Good owners hid their dogs to try and save them. Severe dog and 'pit bull' attacks still occurred, though not often. Dog attacks still happened in general.
What people think is the problem: They're 'pit bulls', used for fighting, therefore aggressive.
What the actual problem is: The breed is a strong one with quirks, and should not be as popular as it is. They're great dogs for the right people, as is the case with any breed (some people shouldn't own Goldens or Labs either, not everyone fits with every breed). They ARE popular despite what is said by some.
My views come from what I have seen, experienced, and studied. Living in an area for most of my life that had a breed ban in effect for most of it, and walking ALL around my neighborhood as all hours gave me perspective that many don't get. There is a LOT that people driving by can't see, trust me. There's a lot you see at night that you will not see during the day. I didn't live in the most run down area, nor was it the best by any means, but the fact that it was kind of moderate should be of note.
Walking home from school, and as I said, walking at all hours day and night, taking my Ibizan on walks...in about a 10 year span, I saw and noted about 16 'pit bulls'. These were dogs that by Miami-Dade laws and how they decide if a dog is a 'pit bull' on 3 different standards(which the UKC APBT standard has been revised as of 2012, but I remember it being pretty vague before then), would have been taken and put down. Goldens and Labs were considered to be two of the top, if not the top, most popular breeds in the country at this time. There were none. GSDs, I saw 3 of, and Chihuahuas came closest to the 'pit bulls' in numbers with 12. Both breeds were in the top 10 of most popular breeds in the AKC as well.
When I moved to a small town in Illinois with no breed ban, breed diversity was greater, which was a pleasant surprise, though having spent less than a year there, I couldn't really get a good feel for the numbers of different breeds and types.
In OKC, where I am now, I see more people walking 'pit bulls' than any other one breed/type. The exception was when I was working at a dog daycare. There were undoubtedly, more Labs, Goldens, and those 'doodles' than just about anything else-and yes, our daycare did allow 'pitties' if they passed the testing. I do see more 'pit bulls' listed regularly on CL, more in shelters if I go for whatever reason, than any other one breed or type. Mixes not included. So after all of this, when people say that 'pit bulls' make up whatever miniscule amount of the dog population they say, I want to call them out on it. Do what I do, see what I have seen, and try to tell me different. They are very popular, and popularity=more poorly bred dogs, more attacks from those breeds, and a plethora of other problems depending on where the breed was at before it was popular.
And for what BSL does...yes, people hide their dogs, as was seen when I was living in Miami. It's not hard to do. When BSL is implemented, the most drastic thing happens at first, which is dogs not registered and what not when it goes into effect...they get killed. There really is no other word for it. Even if the dog has done NOTHING wrong, it's taken and put down. After the heat dies off, the people who have no concern or regard for that dog, or may be using it for whatever reason to make money, be it fighting or breeding...they'll just get them again. It doesn't work. And the people who walk and train and work their dogs, who have social-able, agreeable companions. Their dogs are usually taken first if there is no grandfathering or if they for whatever reason didn't hear about the law changing. If there is grandfathering, there's usually restrictions like the dog have to be locked up, muzzled, can't be taken off the property. And for a dog that was getting out, going everywhere, doing things, being a good canine citizen....it's gotta be hard. It can devastate a dog to be put under such confines. It can turn a good dog into a stressful, antsy, nervous dog who develops issues because of the law. How does that make sense?
Granted, I have seen one of the silliest breed specific laws enacted. Dog must be contained, and if taken off property, must be leashed. Not allowed to roam. WHY IS THAT A BREED SPECIFIC THING?! Why isn't that already a normal 'dog' law?! Was the town/city founded on letting dogs run loose or something? I don't know. But they could have just taken out the breed specific wording and pass it for all dogs. Would have made more sense. -.-
Because you want to know what actually does work?
Not mandatory S/N. Not BSL.
Good general dog laws. Because we should work on lowering ALL dog bites, not just ones from ____ breed. AND! Education. Yes, education, specifically dog bite prevention education because most dog bites do occur in the home.
So I present, the Calgary Model:

Sadly, if you live in a bad neighborhood with people not treating their dogs right and they just happen to be 'pit bulls', they'd either hide the dogs or move onto a different breed if a ban was enacted. I don't think people want those types owning even larger molossiods if they already mistreat their dogs. >.>,,
