I love Pitties. Properly trained, WELL trained, and they're a great dog. Same with any of the big dogs. But, I wouldn't own one, simply because I don't have the wherewithal to give it the time and attention it needs, nor the strength and also because most likely, someone in my house will be allergic to the dang thing.
Corsos are beautiful dogs but same story as a Pittie. When I was a kid, it was the Dobermans that everyone was ####ting all over. In my teens, the Rotties. Now the dog du jour to hate on are Pitties (which is an umbrella name for several breeds - American Pit Bull Terrier, American Staffordshire Terrier, American Bully, Staffordshire Bull Terrier - American Bulldog is also sometimes included).
Presa Canarios are another large breed that have a checkered past in terms of attacks, the most famous (or at least the one most generally well known by people) being the
Diane Whipple attack in San Francisco in 2001. I've met a couple, and they were beautiful dogs, well trained, friendly and fun to play with - although the black ones look like Satan himself has come around in dog form (same with black Corsos).
I hate that with most of these breeds, the breed standard is, or has been, to dock their ears and tails, which tends to make them look even more fierce, which I suppose is the point for some people. I believe that more and more vets are refusing to dock ears and tails, but there will always be some dooosh vet that will do it. I don't think it does the dogs any favours, to know pain from such an early age.
All beautiful dogs, if I had the wherewithal to train them properly and very well, and the strength to handle them, I'd consider it, on private property out of town. I will never ever own any large dog breed of any kind in town/in a city. But, I know that I can't physically handle the breed, and they need a strong owner, not just physically but in every other sense as well.
Oddly enough, 2 breeds I won't ever personally consider owning that aren't a bully breed, are border collies and poodles (of any size). Border collies have always made me uneasy, I find them sneaky and bullheaded and mean. Poodles are vindictive dogs and mean when they want to be just because they can be - we had a couple over the years when I was growing up and they were turds if they got mad at you. We fostered one when my kids were little and he was a royal turd too- we left him at home one day and he got up on a chair and chewed the seat out of it, simply because he was mad at being left at home - but grocery stores tend to take a dim view of anything other than service dogs being on the premises. That was the last time and will never again own one or foster one.
I don't know what the answer is with these large breeds. They need specific training and handling and they don't often get it and THAT is, simply put, the fault of the owner. I used to defend them to the ends of the earth, because often, it isn't the dog's fault, it is the owner. They have no idea how to handle them, or train them, and the dog doesn't get enough exercise or mental stimulation. They end up chained and bored and stressed out. I don't know if the answer is banning them - it's never worked with other breeds that have been in the same boat as Pitties are now. I sometimes wonder if the answer is that the dogs must be specially tagged/registered and owners must exhibit that they are training alongside their animal and provide evidence of such monthly, to animal control wherever they live, and multiple other things. I don't know. Everyone wants the right to own any dog they please, few want to face the responsibility that goes with it and again, that is the fault of the human, not the dog.
However, I do think any breed, you can have a whacked dog - we fostered a small terrier once and that dog was just plain doo-lally, and IMO, needed to be euthanized. What the rescue ever did with it, I have no idea but we took it back to them fairly quickly, because there wasn't a thing we could do to train it, or win it over. It cowered under the bed and constantly crapped/stress diarrhea'd everywhere and snapped at every last person in the house - and my kids were older teens/young adults at the time. I can't imagine how it would have handled young children.
Tough subject. I love critters, dogs especially. But, I know what I can handle/deal with, and what I can't, so....
