A lady near the coast had a coyote come through the doggie door and kill three yorkies. Coyotes are everywhere and they eat small animals. My backyard backs up to open space and I had "coyote rollers" installed on my wrought iron fence. They can't come in from the back but if they are in front of my house they can jump over the front gate. You just had to be very careful.
