One the best thing any one could to temper a pit bull is cross breed it with another type, or hyper vigor.
I would rather have a heinz 57 than any other type of dog.
I had one a child, it had german shepherd in him, it’s mane was like that horse. That was most loving dog who never had any health problems.
I think pure breeding is cruelty.
Nonsense.
Mutts have just as much trouble as any given purebred.
That all is a myth.
It depends on the heritage, and plenty “pure” heritage is good. Although not enough!
