What do you think of Pitt bulls ?

Pits nickname is "the Nanny Dog" because they are most protective over children, And they aren't suppose to way more than 70 lbs the american staff is suppose to be bigger than the pit but people have COMPLETELY ruined the breed and the breed name! they are wonderful dogs bred to hunt and take down boars and bred for sport fighting yes but they are suppose to be wonderful family pets, i had owned one who would sleep and lick my cat, i could use him as a pillow and he was a doll! Its all the breeding people are doing not for the right purpose.
