The following video illustrates what a cornered, anxious, and ready-to-snap dog looks like. If a dog owner ever tells you "Oh, he's fine, he loves kids" but you see

1. lip licking

2. looking & edging away

3. A dog positioned near FOOD of any kind

4. Muzzle-wrinkling show of teeth

5. Stiff, tense body

6. Air snaps or nipping at clothes

GET YOUR KID AWAY FROM THAT DOG. Every day, children are bitten by familiar, "he's friendly!" dogs, after MANY unheeded warning signs identical to those in this video. Anyone who says "It came out of the blue, no warning" is, like the maker of this video, a poor student of canine body language.
