This creature closely resembles a Hound Archon, but is thinner built and with longer legs. In the place of the traditional greatsword slung over its shoulder are a short bladed stabbing sword holstered on its waist and a bandoleer of throwing axes on its lean chest. It is obviously an extremely fast runner

Not all Hound Archons are the blocky, muscular fighters and trackers that are so often seen working as light infantry for the armies of Heaven. Rather, there are as many varieties of Hound Archon as there are of real hounds; all adapted for a different purpose. The Greyhound is one of these, built for speed and endurance to act as scouts, runners, and essentially light cavalry.

Combat

Greyhound are not as strong as their cousins and will try to avoid a straight out fight if possible, preferring to perform hit and run attacks with their throwing axes. If they do enter close combat, they use their shortswords in conjunction with their strong bite; but will generally only do so if they have outflanked the enemy or are attacking lightly armored artillery.

Aura of Menace (Su): Will DC 16 negates

Change Shape (Su): A Greyhound Archon can assume any canine form of Small to Large size. While in canine form, the Greyhound loses its bite, slam, throwing axe, and shortsword attacks, but gains the bite attack of the form it chooses. For the purposes of this ability, canines include any doglike or wolflike animal of the animal type.

Spell-Like Abilities (Su): At will-aid, continual flame, detect evil, message

Trip (Ex): A greyhound archon that hits with its short sword 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 greyhound.

You can find the rest of the subtypes for every Archon by looking for Dice's post earlier on; I've been meaning to save it but haven't got around to it yet.
