Keep yourselves and pets safe. Pepper spray works against coyotes! Get ready to spray, hold your own breath, close your eyes and turn your head away. Give a good blast to the attackers eyes or face if possible.
This works on most wild animals, except snakes or birds. (Your own pet will recover from the spray, but it does hurt for a while. But it beats being bitten or dragged off.)
Maybe we need to sew armor plating into dog sweaters??
