Dog (Fallout: New Vegas)

Dogs are creatures found in the Mojave wasteland in 2281.

Background
Dogs in Fallout: New Vegas appear in many different forms. Most notably as the companion Rex, a cybernetic dog owned by The King in Freeside. They also appear in many ways as attack dogs for Caesar's Legion, New California Republic, Old Lady Gibson, Sunny Smiles and the Fiends. Vicious dogs and other members of the canine family (coyotes) also make an appearance. Neutral dogs may also be found (simply named 'Dog') one of which may be found wandering outside of the NCR Correctional Facility.

In the quest Nothin' But a Hound Dog, the Courier must locate a replacement for the deteriorating brain installed in the cyberdog Rex.

Biology
Through the 200 years since the Great War, dogs have remained unaltered by radiation, which is seemingly a miracle. Other than that, there is no reason to believe that the biology of dogs in the Fallout universe differs from dogs in the real world, besides having a rougher appearance than domesticated dogs, unsurprising in the harshness of the Wasteland.

Gameplay attributes
Legion mongrels & NCR guard dogs will attack players that have low reputation with the NCR and Caesar's Legion respectively, vicious dogs along with Fiend guard dogs will attack players on sight regardless of reputation, wild dogs will attack if the player is close enough to make them feel threatened.

Dog
Regular dogs with standard statistics and characteristics but no special attributes. Large dogs don't differ much, aside from being stronger than the basic variety. Regular dogs roam Zion Canyon. Old Lady Gibson owns 6 of these animals to guard her junkyard.

Prospector's dog is a rare variant that is found in only 3 places, Smith Mesa Prospector Camp, Ivanpah Dry Lake and El Dorado Dry Lake.

Legion mongrel


Legion mongrels are dogs owned and bred by the Houndmasters of Caesar's Legion. Mongrels are mainly used in combat and scouting missions by the Legion. The current mother of the mongrels in The Fort is Lupa. Because of their thick, shaggy hair (as seen on the picture) and their red-colored eyes, they are of a distinctly different breed than most dogs found in the game. Their appearance more resembles that of a wolf or coyote. While most of them are bred, Antony says the Legion sometimes finds good mongrels in Denver, the Dog City.

NCR guard dog
The breed commonly used as guard dogs looks similar to the vicious dogs that roam the Mojave Wasteland.

NCR guard dogs are widely used by NCR troopers and are similar to the Legion mongrel. They can be seen patrolling Camp Forlorn Hope and HELIOS One with NCR soldiers. In the quest You'll Know It When It Happens, if you have the Animal Friend perk, Ranger Stevens will agree to lend his dog to the player, allowing him to discover the undercover member of Caesar's Legion with the detonator for the bomb placed aboard Bear Force One. Some dogs are in the shack with terminal B at Helios One.

Vicious dog
Vicious dogs are a nearly hairless species of wasteland canine, apparently pitbulls. Ruthless survivors of the wastes, these starving irradiated mutts will attack anything that moves, including you, unless you have acquired the Animal Friend perk. Vicious dogs are also known to hunt in packs. They resemble the vicious dogs featured in Fallout 3.

They resemble the guard dogs used by the NCR, and Fiend guard dogs used by Violet.

Wild dog
Wild dogs and large wild dogs can be found near the NCRCF. They are rarely hostile and will only attack the player if they get too close or if the player provokes them by attack them first, or one of their pack.

White Legs mongrel (Honest Hearts)
White Legs mongrels appear throughout the Zion Canyon, accompanying members of the White Legs tribe. They will attack once the player is spotted. They are identical to the Legion mongrel, which would indicate that Caesar gifted them to the tribe, undoubtedly for the purpose of destroying New Canaan.

Appearances
Dogs appear in Fallout: New Vegas and its add-on, Honest Hearts.
