Firstly, it is important to note that Cerberus is a specific type of creature, and not a generic Zombie Dog
- which was the result of a random t-Virus
infection on a regular dog via an outbreak. The Cerberus was scientifically engineered as an early B.O.W (Bio-Organic Weapon).
Cerberuses are Doberman pinschers infected with the β strain of the t-Virus
, an early attempt by Umbrella to create a deployable B.O.W. for sale to the military.
Initially considered a success by Umbrella, trouble began after the initial t-Virus
outbreak in 1998, where they escaped. Without a supply of food or training to keep them from becoming too aggressive, they turned feral and began attacking and eating anything they could find.
The dogs themselves have typical t-Virus
characteristics such as decomposing skin, enhanced durability, heightened aggression and very little in the way of reasoning. However, with the right personnel, Cerberuses can be trained to follow orders. Unfortunately it was far too late after the outbreak.
