Similar to dogs, coyotes do not appear to have been visibly altered after the Great War, possibly due to sheltering from radiation.
Gameplay attributes
Coyotes are very territorial and will attack the player character if they stay near for too long. Coyotes are usually found in packs of up to three or four in the more desolate areas of the Mojave, especially caves. They are slightly stronger than dogs, but do about the same amount of damage.
They're not much of a threat to well armed players. Characters at lower levels or those playing on higher difficulty may have a difficult time, especially if taking on large groups.
Variants
Coyote
Regular coyotes are the most common of the coyote family. They can be found in almost every corner of the map, but primarily along the I-15 and two packs are near Goodsprings Cave with another pack inside. One group can be found down the hill from the entrance to the hidden supply cave, and another group can be found close to the Canyon wreckage entrance.
The offspring of a coyote. They are smaller and weaker than normal coyotes, on par with radroaches in terms of durability, and are rarely a hassle even for low-leveled players. They generally stay close to the den mother. If the player gets too close they will attack along with their parents.
Coyote den mothers and alpha males are significantly larger than they would appear in real life. In reality, they would appear slightly larger than a dog.
Coyotes will always growl before they attack.
Coyotes will growl when approached, but will not attack if the player backs away, even if noticed.
All coyotes share the same model with grayish coats, differing only in size, with pups being smallest, coyotes slightly larger and den mothers being the largest.
Coyotes are friendly to the player if the player has the Animal Friend perk.
