Dog Proof. Either Dukes or Bridgers. I prefer the bridgers just a bit over the Dukes, seem to have a more sensitive trigger.
Crazy easy to set and take up.
Lots of folks stress out about having them close to a tree, but I actually anchor mine to a tree and haven't lost a trap yet (I did lose one coon to a ?coyote... checked it the next morn, found a coon paw and forearm bones in the trap, so obviously some predator took the coon.
I take a piece of quarter inch cable and put clasps on each end. Wrap the cable around the tree and clasp it around the cable. The other clasp I attach to the trap.
Advantage of that setup is I don't have to tap in or remove an anchor. It literally takes me 30s to set a trap, and 30s to remove one.
The disadvantage is that the coon has often wrapped itself around the cable and tree and is completely immobilized by the next morn. Easy to dispatch, but takes a minute to untangle the mess. Haven't lost a trap yet.
