According to anciend legend the foloowing things are sigs of being a werewolf. First, their index finger is longer than their other fingers. This is due to the fac that the hand transform into paws.
Secondly they have patches of dense, and unusually think hari in places tha most people do not have hair (palms, bottoms of feet, between fingers and toes)
Third unusually hairy and bushy eyebrows that come together in a point down on the nose farther than normal hair would grow.
Fourth, unusually white teeth, especially in persons who have prominent dental problems.
Unusally accute senses, especially hearing and smell.
When they eat they tend to rip and tear at food with their side teeth in the manner of an animal rather than biting head on like people.
Those are the most common signs that someone is a werewolf. There are some more obscure ones and, if you're interested you can e-mail me here and I will pass them along.
