rsh - I take the same approach with my donut of a dog. He couldn't fight his away out of a paper bag and would rather have his belly rubbed than take a chunk out of someone but unfortunately his "look" is enough for some people to have a perception of him.

Numbers - Those are all valid as well. I was trying to reassure Pico because reporting a dog simply because it's big and off the lead seems a bit OTT.
