The hunting hound first appeared in Dragon #102,
A Collection of Canines, by Stephen Innes. I don't have the magazine, but I worked from the SRD entries of the riding dog and wolf. (I've got a ranger who just hit 4th level and I want a deerhound for an animal companion.)

Wolves are pack hunters known for their persistence and cunning.
Combat
A favorite tactic is to send a few individuals against the foe’s front while the rest of the pack circles and attacks from the flanks or rear.
Trip (Ex): A wolf that hits with a bite attack can attempt to trip the opponent (+1 check modifier) as a free action without making a touch attack or provoking an attack of opportunity. If the attempt fails, the opponent cannot react to trip the wolf.
Skills: *Wolves have a +4 racial bonus on Survival checks when tracking by scent.
