I just have to stick my experience in here, I've worked for a vet for 15 years and managed never to get bitten, until last Tuesday, by a Maltese. Little guy ran right up to me and bit me on the calf!
Now I'm not generalizing, just want to add be sure to socialize your puppy with lots of different people and situations, the one who bit me USED to be momma's little baby, until she had 3 children, and now the dog spends most of the day locked in the laundry room behind a child safety gate, NOT because of aggression, but because she "just doesn't have the energy to deal with him".
You wouldn't believe how much it still hurts!
