Coyote

It has an intermediate appearance between a wolf and a jackal.

An excerpt from the article 24 facts about Coyote

It is smaller than the gray wolf (Canis lupus) and slightly smaller than the eastern wolf (Canis lycaon) and the red wolf (Canis rufus).

It occupies the same ecological niche as the golden jackal (Canis aureus) in Eurasia, which is why zoologists sometimes call it the American jackal. However, it is larger and more predatory than the golden jackal.
