Coyotes can attack humans but they rarely do.
The coyote is a species of canine native to North America.
It is smaller than its close relative, the wolf, and slightly smaller than the closely related eastern wolf and red wolf.
It fills much of the same ecological niche as the golden jackal does in Eurasia.
Yes wolves and coyotes are related closely to each other.
The same goes for domestic dogs as well as domestic dogs and wolves and coyotes are also related to each other very closely.
Dogs, coyotes and even wolves can all mate with each other and can interbreed and produce viable, fertile offspring together.
Also through DNA analysis, scientists have established that the wolf is the ancestor of the dog.
So when you see a dog or have a dog it's an ancestor and relation to a wolf and a coyote.
