It’s bad when a coyote and a domestic dog breed....the offspring form a pack and run together to hunt. And they have no fear of humans...in fact they know humans will “feed” them by having farm animals and pets for them to eat. And they will attack the humans as well. There was a pack (about 12-15 animals) that ran near my farm years ago. You would hear them just after sunset coming through the fields or woods, howling and yipping. If I was there feeding the animals when they came, I would go in the barn and close the doors until they left. Often, they would go in my neighbors pastures after the cattle...but the neighbors kept donkeys in the pastures to protect the cattle...donkeys will chase and stomp coyotes and coy-dogs to death. Interesting series of sounds in the night: Coyotes and coy-dogs howling; cows mooing restlessly; donkeys braying as they stomp; coyotes and coy-dogs screaming as they get hoofed to death; then, total silence.
I have noticed more and more people keeping donkeys around here. I guess that is why.
