I suggest each know the laws of their state on the control of loose dogs.
That's very good advice.
Here in Ohio, it's against the law to hunt deer with dogs. The game warden will tell ya, if you see a dog/dogs running deer to shoot them. This area,as with many, is a dumping ground for unwanted pets. The strays will form packs and start running deer/livestock for survival. Most of the farmers around these parts are familiar with each other dogs so if someone sees my dog running deer, I would get one warning. After that, the dog would be shot if seen running them again. Running livestock doesn't get a second chance.
