I have trapped a bit just for fun. And it's been a while ago too. Coons mostly, they're easy and possums are too. Never tried for a possum but have caught a bunch of them. Pesky critters. I assume by canines you mean coyotes? Be careful, you'll catch the neighbors dog. I never have caught a coyote in my legholds but have snared a few. It's fun, but time consuming. Hard to do for me now. I know a guy at the metal shop up the road that runs his traps everyday before work, mostly by flashlight. He's dedicated.
