Parents, please teach your children about the Do Not Disturb sign above dogs that are sleeping and/or contained. Dogs that are sleeping can startle if touched and should be allowed to sleep in peace. Contained dogs (like a dog in a crate, behind a gate, on a tether, or other enclosed space) have no means of escape from hands encroaching on their space and may feel a need to react with a growl or worse to get someone to back off. This is one important way you can help to prevent dog bites.
