Whoever above said “idiot magnet” was right. Those XXL Bullies attract people who have neither the time nor ability to look after such a dog.
There are loads in my town and all owned by people who can barely organise their own lives let alone a dog’s. I even met an XXL in the park being taken for a walk by two primary age children. It had, unsurprisingly, pulled out of their grasp and was running around like a lunatic. I was terrified. I and two other members of the public managed to get hold of it’s lead, and only then saw it didn’t even have a proper lead or collar, just home-made, totally inadequate rubbish that a chihuahua could have pulled out of.
XXL Bullies, Canó Corsos, anythingof that tupe should be banned for general ownership and only licences did professionals allowed to own them and in very limited numbers. Rotweillers and Dobermans and GSDs again should be licensed but possibly a tier down eg public can own but need to undergo and pass training courses.
Or we could simply go by weight and anyone owning a dog above a certain weight needs a special permit. I know all dogs can bite, but it’s the weight that dooms their victims.
