Horses lack incisors, so horse bites often look like large inflamed or bruised areas that may or may not have flat indentations on a circular pattern, where teeth connected. This pattern is most easily seen on fleshy areas of the human body, like the stomach, thighs, or shoulder. When a horse bites a hand or head, however, it is harder to say what the bite will look like. Horse bites vary in appearance according to how hard the horse bit down, how fresh the wound is, and where the person was bitten.
