They’re not suitable for every one.
A dog and its owner need to be matched on personality and temperament.
People like cute puppies but a young adult dog is far less work has already been trained and you know what its personality is like.
People need to put as much work into finding the right dog for them as they do in picking their spouse.
Too often, pit bulls and their owners ARE matched up in terms of personality and temperament. That’s part of the reason why pits have the poor reputation they have. The rest is genetics. Pointers like to point, herders like to herd, pits light to fight and kill.
I've seen enough evidence over the last forty years to convince me that pit bull terriers aren't suitable as domestic pets for anyone.
