This papercraft is the Cerberus, a B.O.W. series developed in Umbrella labs, such as the Arklay Laboratory, from a doberman pinscher infected with the Tyrant virus, based on the horror media franchise Resident Evil (known in Japan as Biohazard), the paper model was created by Jp-papercraft.
The Cerberus should not be confused with "zombie dogs", which encompasses all dog breeds infected with the t-Virus in the secondary form. Pronounced as the Greek word, 'Kerberos'; this creature was named after the mythological guardian of Hades, a gigantic dog with three heads and a collar made of venomous snakes. [Source: wikia]
