Cyberdog (Fallout: New Vegas)

"If you think braving the cyberdogs of X-8 makes you... brave, intruder. It is no use. All cyberdogs are under my command, and they will bite you."

- Dr. Mobius

Cyberdogs are creatures in Big MT and the Mojave Wasteland.

Cyberdog
The Cyberdog is a non-militarized version of the Police/Military Cyberdog. It was most likely used for companionship rather than combat, as it relies on it's speed and bite strength alone for defense. When traveling to Fortification Hill, speaking to Antony will trigger a comment that he has seen similar cyberdogs in Denver, Colorado, if you are traveling with Rex as a companion, and will offer up his dog Lupa's brain, through combat, to use as a replacement for Rexs' aging brain.

Military cyberdog
The military cyberdog has a sonic bark used as a weapon, and has a chance to knock down the player with its melee attack. They also seem to have the ability to self heal themselves, similar to the MKII Securitrons.

Police cyberdog
A slightly weaker variety of the military cyberdog, police cyberdogs may contain several types of small energy cells on death. They can be distinguished from military cyberdogs by their unique black and white paint, as well as the red and blue reflective patches on their back.
