I will not indescrimanently shoot dogs crusiing the woods. Dogs will be dogs, and woods cruising is in the blood of some, for sure.
However, feral or what I'd call "semi-feral" dogs packing up around where I hunt have been an issue for decades. If they look rough, they are goners. Have collars ... I let them walk. If they are not collared but appear fat 'n happy, I let them walk. I'll run them off if I can but not shoot 'em.
