I mentioned coyotes being friendly to dogs to lure them to the pack where the dog is attacked and usually killed. Coyotes are knows for doing this in parks where people walk their dogs and also farm land where there are farm dogs. A pack tried to fool dad's dog, but thankfully he did not take their bait.
Here the roles are reversed. The dogs act friendly towards the coyotes and bring them closer to the shooter.
