I never got into trapping all that much growing up but my great granddad made his living hunting and trapping. One thing I CAN tell you RR is that a snare or foothold absolutely WILL hurt a dog. I had to take one of my Beagle hounds to the vet to have it's foot finished off removing. He hit a snare at pretty much a dead run. And your trying to say a jaw type foothold wont hurt a dog? Barely slow a hunt? You obviously have NO clue about traps. Now granted a smaller one such as a #1 or #1 1/2 may not injure a dog (and the 1 1/2 could on a smaller breed like my little Beagles) but you start running into sets of 2's 3's and 4's and you will have a hurt leg for sure. and 1 1/2's and 2's are recommended sizes for coon traps if I remember correctly.
