Zombie Dog (Resident Evil 2)

The zombie dog, unlike the Cerberus, was not an experiment, but more of an accident. When exposed to the T-Virus, the creature mutates. However, the movements and attacks are practically identical to that of the Cerberus.

The easiest way to deal with these dogs is by using the handgun. Wait until they come at you, and fire a single shot. Wait until they stagger to their feet and prepare to pounce, then fire again. Keep repeating until they're dead. The problems come when you're surrounded, as their jumping bite attacks could be fatal if delivered one after the other constantly.
