Breed bans do not work. People will either buy/breed them illegally, or simply replace them with another large breed. (In the US, bloodhounds were once considered a problem breed. Then it was German Shepherds, then Dobermans, now pit bulls. Recommended reading:

It is an issue of training and vigilance. In other words, it's a people problem, which is a lot harder to fix.

@TomeReader I agree. It’s a people problem that will be much harder to fix. One of my pit mixes is dog aggressive. I hated the idea of muzzling him when we go out in public but I worked with a fear-free trainer and he learned to put his face in it on his own and now doesn’t seem to notice it at all. Education for me as the person responsible for his well-being and behavior was key. Training for the person and dog takes time and a lot of people won’t be willing to put in the work.
