Heres a couple pics of a wolf I caught in a coyote set. I usually catch a couple a year and with no tag have to release. This one had a collar. The other is a comparison pic of a wolf and coyote showing the difference in size. As far as coloration they are identical. Wolf weighed 68# and the coyote weighed in at 34# .
And a wolf vid of one I released with a collar.
