Poodle--many bites, one serious
Schnauzer--snappy but never really bitten
Siberian Husky--no bites

Many years ago my sister bent over and tried to take a bone from Smokey. He jumped up and severly bit her face, to the point where she required plastic surgery on her nose. I think we were advised to put him down, but we didn't. My sister was aware he'd bite, and she was the idiot who tried (she was teasing him) to take the bone away. He bites at people all the time, but well, he's a 17 year old grumpy dog, and luckily, they don't hurt because he has basically no teeth.
