I caught a big yellow lab a few weeks ago. He just layed there. Even after I let him loose he wouldn't run off. I had a few more to check and when I got back he was gone. I hate catching dogs. He had jammed the trap levers some how and I got my hammer out to try and release them to let him out and layed my hammer down and picked it back up and grabbed a handful of dog crap that I had layed the hammer in. That hammer still stinks.
