Coyotes are sly and vicious predators and will attack anything they think they can kill, she should install at the very least motion detection lighting as bright as possible in her back yard and or consider installing an automatic sprinkler system linked to a motion dectector. Make sure the coyotes have nowhere they can lie in ambush as well if possible. Animal lover or not she should have a firearm handy in case she herself is attacked (it's happened repeatedly already even in the suburbs of Los Angeles!) if she doesn't wanna kill them a 20 ga with a load of rock salt will discourage further visits at least by that particular coyote.
