After getting permission to pet a dog, always let the dog sniff the back of your hand first. When a dog approaches you, stand still and stay quiet. Keep your hands at your sides. When you are not walking your dog, keep him indoors with you or in a fenced yard. Spend time playing with and caring for your dog.
Pets naturally guard their food, their babies, and their toys.
Dogs also protect their owners, as well as property that belongs to their owners such as an owner's home, yard, or car. Don't try to pull a toy, a stick, or any other item from a dog's mouth. Playing roughly with dogs may teach them to bite, jump, or become aggressive. Don't run away from a dog who is chasing you. Also, don't chase or tease dogs or cats, and avoid petting or trying to pick up strange pets.
