     Nearly 5 million dog bites occur in the US each year, according to the American Humane Association. Ms. Stilwell, CEO of Victoria Stilwell Positively Dog Training, offers some advice on how to read dog behavior to avoid an attack on a person or the other dog.     People are usually attacked by a dog they know, "It happens when the relative has brought his dog over, or it happens at a friend's house," says Ms. Stilwell, "We just let our guard down here."    “Obvious signs include barking, growling, if the dog's ears are flat or suddenly prick up. Some dogs salivate(流口水) when they are stressed, others cower(畏缩),” says Ms. Stilwell. "Dogs will wag(摇) their tails when they are upset or over-aroused." Similarly, if an unfamiliar dog rolls on its back to expose its belly(腹部), it doesn't necessarily want to be petted. It might be asking you to move away.    A dog that attacks is often acting out of fear, says Ms. Stilwell. Those signs of fear may include a dog yawning, turning its head away when someone approaches, tensing up or staring. Some dogs will slightly lift what Ms. Stilwell calls "the anticipatory paw (先行爪)," because it shows that they think something negative is about to happen. Another subtle warning sign is when a dog slightly lifts its lip to show teeth. Also, when a dog’s flat tongue is relaxed or curved at the sides, it means there is tension.    "If a dog is on a child and you're pulling it off, you're making the wound on the child deeper," Ms. Stilwell says. Instead, "take a coat or T-shirt and put it over the dog's head," she says. When dogs can't see, they panic and open their mouths. 46. We can conclude from Paragraph 2 that we ________.
