Chevy here's a pic. The snare loop is outlined in photoshop red. This is a 5-foot cable snare anchored to the pine at left with a 4-foot extension cable connected by a quick loop for fast change-out of the snare after a catch. Roughly a 10-11 inch snare loop elevated 11-12 inches off the ground.

All the vertical "brush" between the two Pines is added by me. Basically it's twigs trimmed off nearby hardwood shrubs. I want a thin screen, enough to deter the dogs from walking around the snare, but thin enough so they can still see through and won't sense anything is out of place. Just enough brush to route them directly into the loop.

I don't try to make the dogs go places they don't normally go. I find general areas they have a tendency to pass through, then add the brush clippings to boost the odds their head finds the loop. Snares are cheap so find every spot imaginable they might walk through and put a snare there. You'll eventually figure out the best spots and then you won't need as many snares.

A lot of time you need to stand way back and look over an area from a distance to identify potential travel corridors. Then squat down low to get a Coyote's-eye view so-to speak.

Also some fresh snow will tell you a lot. I never miss a chance to walk the farm a day or two after a snowfall for sign.
