A hell hound is a big, powerfully built dog with short, rust-red fur; its markings, teeth, and tongue are sooty black.

Physical description
Hell hounds are the dogs of the Nine Hells. They appear to be canines with emaciated features and fire spouting from their red glowing eyes and mouths. The average hell hound stands 4 1/2 ft (1.37 m) at the shoulder and weighs about 120 lb (54.43 m).

Combat
Hell hounds prefer to hunt in packs and will use their fiery breath on an opponent first and then close in for the kill.

Ecology
While hell hounds are found in the Plane of Hell, they are also regularly seen in the Plane of Fire and the mortal world. Fire giants and other fiery creatures make use of hell hounds as guard dogs and hunting beasts.

Society
Hell hounds use wolf-like tactics. They organize in packs, surrounding their prey, and attack one at a time until the target becomes fatigued or falls to the ground. If singular attacks do not seem to be effective, the pack will each breathe a gout of flame at the target. The pack then charges in all at once to slay their prey with fiery bites.
