Tough call,
is this private land? or public?
if these are domestic dogs, not sure of laws for running dogs ,
believe most places owners are supposed to be within a certain distance,
if these are wild dogs they would be open game like any other predator hunting,
if it was a 1 time thing i would let them go,
if its a recurring problem on private land i would take them out,
if its on public, i would do my best to determine wild or domestic,
if domestic and owners are legal would try to find them and work with them,
if owners are running dogs illegallly, would try even harder to let game wardens know of illegal dog running,
wouldnt take out owners illegal activities out on the dogs
