You have to be very careful with kids though... they dont always understand that a dog can turn in an instant... ANY dog.
Had a Border Collie when my boy was small, then one day while my back was turned he put one finger up its nose.. dog turned and bit him on the face taking a chunk of skin out beside his eye... my son is scarred for life after this on the left eye.
It happened in a fraction of a second and was all over before i could even turn a round... thats a Border Collie.. would hate to see a Staffy turn
Agreed, I will never forget when I was a little kid, our beloved Labrador taking a chunk out of my father's face in front of me (leading to a trip to hospital and reconstructive surgery) - we never understood why, they were playing as they had for years, and something upset the dog, and it bit its master.
that's why I don't put my face too close to my wife anymore.....she's getting a bit long in the tooth
