If you're a wolf.
Some dogs have those too.
Yes, No matter what you compare, if a person has their heart set on finding things, they will, even if there is nothing notable.
Yes..it is possible.When theres a ful moon I tend to go all Wolfy. You know how that goes..howling, loudly and then busting out the window to get free of this HEAT (Lawd I get so hot!)...my nails get even longer, and my teeth get incredibly long...Thank God this only happens occasionally...
Depends on whether you are talking about the physical features or the psychological features. I have seen one guy on NAT GEO who has got himself tattooed and operated upon to resemble a wolf or a tiger or something. I doubt if he has got a brain implant too.
