J vs C dog

The MA-39 Cerberus was a B.O.W. developed in Umbrella Chemical, Inc. labs - such as the Arklay Research Facility - from a Doberman injected with the experimental tyrant virus. It was given the development code of MA-39 (a similar code to that of the Hunters).
Although suffering from a similar necrosis to human's infected by the t-virus, Cerberi retain much of their former agility, with a noticeable increase in durability and aggression. Cerberi' were also created accidentally in the t-virus outbreaks of Raccoon City, Sheena Island and Rockfort Island. In all such cases, contaminated meat was the likely cause of infection.
What else needs to be said? It's a frickin' zombie dog!
