OK.. I hunt public land, and if I saw a dog without a collar I would shoot it because they will probably starve anyway and wild dogs are a problem in GA, and legal to shoot.

Except this happened a few years ago.. the dog walked up to me wanting food and I just couldnt shoot it.. so I gave him some of my sandwich.

I wouldnt shoot a dog with a collar.. but the owners are a-holes if they let their pets on public hunting land.
