I sounds as if people in your area, and maybe others, need to have a coyote killing dog to protect the smaller ones.
I hear about people out walking dogs on leashes having their dogs attacked. Some wildlife experts suggest people carry bear spray to fend them off, but that sounds unfeasible since most dog walkers would not carry anything as bulky as a can of bear spray, and it could be hard to use it effectively as they come in for the attack.
