From any distance, the tail. The rest may be "iffy", but there isn't a domestic breed with a tail quite like a coyote. Up close, the crotch. Most dog breeds don't have dense hair on the belly between the hindlegs. It either looks like one or it doesn't. Shoot it. Look at it. If it is, take it home. If it ain't, dig a hole. /ubbthreads/images/graemlins/smile.gif I've only seen one truly all white coyote and it was known to be part dog. Had him at thirty yards on green winter wheat and couldn't shoot becasue the property owner had made me promise not to kill "his white coyotes".
