I have two labs and two kids. The dogs are great with kids. My son has put his thumbs in the dog's nostrils, woken him up by pulling on his genitalia, taken food out of their mouths, my daughter will climb on them while they sleep to give them hugs, run her doll's stroller over their paws and tails and the worst the dog has ever done is a little growl. No snapping, no biting, nothing. Growling, at least in my book, is a good thing, because it is the way a dog sends a warning and is very effective of inter-species communication.
