Korovia - The Free License Fantasy World
The Wolf-dog is the most common dog in Korovia. It looks like a small white and/or black wolf, weighing between 30 and 50 lbs. They have a +4 racial bonus on Jump and Survival checks. A Wolf-dog can attempt to trip opponents as a free action like a regular wolf, but has a –3 check (-4 size, +1 strength). If the attempt fails, the opponent cannot react to trip the Wolf-dog.
Wolf-dogs make good pets and viciously defend their owners. They are often owned by hunters or shepherds and used for tracking deer or finding lost sheep. Some wizards have Wolf-dogs as familiars.
