re: Do you think dogs instinctively know coyotes are dangerous?

There is a creek bottom across the road from my house where coyotes run 3-4 times every night. When my dog hears them, she goes out and lets them know she's there (she does not allow animals into her turf). She won't go after a pack and they won't go after her on her own turf. She will pursue a single coyote out of the cow pasture behind my house.
