I had a staffie, best dog I or the family ever owned, when my eldest son was born the dog, whilst never left alone with my son, was as gentle as could be, even as my son grew to be a toddler the dog was ALWAYS on the side of the child, when playing with my son on the floor the dog would always let me know if he thought my playfulness was too much for my son, dog slept outside my sons bedroom door so from personal experience with one particular dog I do not believe staffies to be bad dogs, would definitely have another if circumstances would permit ownership of a dog.
