What Is The Difference Between A Coyote And A Coywolf?

What Is The Difference Between A Coyote And A Coywolf? I have previously found coywolves to be significantly different in body size from both western coyotes and eastern wolves. However, they are closer to coyotes whereby eastern wolves are 61-71 percent heavier than the same-sex coywolf, while coywolves are 35-37 percent heavier than western coyotes.
