There are 4 million dog bites each year and 60% of the victims are children. Dr. Leslie Sinclair of the Humane Society of the U.S. says children often don't respect a dog's boundaries—they expect every dog to be friendly, and although most are some aren't. Dr. Tillman Jolly, an emergency room physician says he sees injuries every year because children often do things that they don't realize are annoying to dogs. The Insurance Information Institute cautions that parents should teach their children not to approach an unknown dog. Allow dogs to sniff you before petting them, never disturb a dog that's eating, sleeping or caring for puppies, don't try to run from a dog, and if one is chasing you, stand like a tree or look like a log. Insurance companies paid out $3.5 billion in claims in 2006 for dog bite claims.
