The Aardwolf is a smaller version of the Giant Aardwolf. The fact that Titan has "Giant" Aardwolves would suggest that the normal Aardwolf also exists on Titan, though none are ever mentioned in canon. Having said that, a Giant Aardwolf was found in a kennel in Shaggradd's Hives of Peril, and in this instance the terms Giant Aardwolf and Aardwolf were used interchangeably.
