Coyote

Coyotes almost always travel in packs like their wolf cousins. They have sharp teeth and will frequently knock a target over, then attack the head.

They are a bit stronger than the dog but weaker than the wolf.

Fallout: New Vegas
Coyotes return in New Vegas. They are hostile animals.

Appearances
The Coyotes appear in Fallout and Fallout: New Vegas. They were also going to appear in the canceled Fallout: Brotherhood of Steel 2.
