If they where my leg hold traps they'd hurt, even the off sets with rubber, will be a pain if the dog has large bone. Closed gap is less than 1/2". Snares would be worse IMO, they are quick if the dog struggles (thankfully most "people dogs" don't freak like a coyote.
Have some damn good cutters, as most good ones (snares),are aircraft cable. I would bet a snare would be left behind before a $50 jaw trap as well.
Will usually find snares on a fence row. jaw traps usually on a trail or roadside edge.
If it is a state or government trapper (which I would doubt) they usually post signs warning that traps are in the area and always when using the m44 sodium cyanide spring loaded trap.
I would really doubt that there would be traps out there though, to costly and time consuming to risk the loss.
