Never approach an unfamiliar dog, especially one who's tied or confined behind a fence or in a car.

Don't pet a dog, even your own, without letting him see and sniff you first.

Never turn your back to a dog and run away. A dog's natural instinct will be to chase and catch you.

Don't disturb a dog while she's sleeping, eating, chewing on a toy, or caring for puppies.

Be cautious around strange dogs. Always assume that a dog who doesn't know you may see you as an intruder or a threat.
