Okay, I will bite. They may be cute and adorable, but their physiology makes them dangerous. It’s akin to taming a lion or tiger. You might think they are docile, but once they strike, they do a lot of damage.
These dogs are dangerous animals, because they ARE STRONG.
They are dangerous for several reasons not just because they are strong.
A ridgeback is probably stronger but is a much safer dog to have around. Because they are controllable.
Once a pit bull goes into kill mode there is very little you can do to controll it. It will keep killing until it is sated or until something kills it. Their strength of course is a major factor in people being unable to physically control them.
