We have a wide variety of predators that have come in here. Cougars, brown bears, coyotes, eagles, hawks, raccoons, weasels. The dogs help discourage the bigger ones.
I've only lost birds to neighbor dog, hawks, opossum, and weasels. The dog isn't an issue anymore as they left it to wander and it got hit out on the main road. The opossum was harrassed off by my dogs and I set weasel traps and set the dogs in the locked pen for a while.
Only garter snakes here. I have to save them from the cats occasionally.
