Canine Track

Met my neighbor on the trail today and he said before the big storm there had seen a wolf track coming down the same path we were walking. But this picture, I'm pretty sure, is Indy's from a some time ago. It's definitely canine. You can see the claw marks at the end of the toes. The top of the heel mark is a single lobe while the bottom the heel mark is two-lobed. They are probably a dog's since the print is generally round. Also a wolf's track would be about twice as large as a medium size dog's. I would like to get a picture of a wolf track - preferable to meeting the real thing in the woods.
