One of the easiest and most important things that you can do is to not leave your younger children alone around a dog, not even the family dog.
Carefully choose your pet dog. Evaluate your environment and lifestyles and speak with a professional to determine the appropriate type of pet.
Dogs should be neutered to reduce aggressive tendencies.
Be sensitive to cues that a child is fearful or apprehensive about a dog.
Teach children basic safety around dogs and review regularly.
Dogs with histories of aggression are inappropriate for families with children.
Never approach an unfamiliar dog. Immediately report stray dogs or dogs displaying unusual behavior.
Remain motionless when approached by an unfamiliar dog -- never run or scream.
Do not disturb a dog that is sleeping, eating, or caring for puppies.
If bitten by a dog, immediately report the bite.
