I've had trouble with coyotes, fisher cats, raccoons, opossums, other folks dogs,& fox.The occasional bear/bobcat wanders thru my area but never bothered me. The dogs also keep deer, rabbits, squirrels, chipmunks and woodchucks out of the garden. They once caught a neighbors pig that got out & held it until I could drag it into a pen & call the neighbor. They are pretty handy & good company as well.
