Sorry to hear this. Buddy of mine lost his 1 year old this way. Leaving a coat is a good idea. Not sure on firing the shotguns. Sometimes where I hunt coyotes come right to the sound of people shooting hoping to clean up on jackrabbits. I called a pair of coyotes in while my friend banged away with his 12 gauge just 100 yards away. Depends on the coyotes exposure to this.
Drive all the roads, scan with a spotlight to catch the dogs eyes. Man, really sorry to hear this.
