Weredog

A weredog was a lycanthrope that could transform into a large dog. They were often confused with werewolves.

Description
Such creatures were able to transform into dogs such as mastiffs, or St Bernards. Most often, these weretypes were good-willed. Weredogs chose werewolves as their enemies, and swore to defeat them, despite being less numerous and powerful.

Combat
Weredogs attacked their foes with a powerful bite, which also transmitted lycanthropy.
