Coywolves

Referred to as a Human-Made-Hybrid the coywolf is the hybrid of a coyote and a wolf. Seen in America's  Northwest regions and parts of Canada the first coywolf hybrids was created an estimated 50-70 years ago due to habitats being destroyed by deforestation and others forms of human interaction. With wildlife experts estimating  millions of theses new animals existing they can pose a threat to nature and humans. (wolves- have strong jaws and an intelligent pack mentality yet avoid humans to protect their own while coyotes are more likely known to wandering into rural towns and show aggression towards humans).
