The trash people dump out at the end of gravel roads are usually easy enough to take care of. It's when city people move out in the country to their 5 acre "ranch" and let their mutts roam all over the country side that it becomes a problem. Just the other day I found two that had a hog bayed in a livestock tank chewing it up. I've counted as many as 8 in a pack before. Sometimes they make it back home, sometimes they don't.
