The Hellhounds known as Pinkies are much more intimidating than they are dangerous. Their primary mod of attack is a bull-like charge, followed by bites and stomps. If you've got room to avoid the Pinky's charge, it's a relatively simple matter to take it out before it can lay a paw on you.
The Hellhound is a monster found in Doom RPG belonging to a demonic class known as Canines. Hellhounds are brown members of the species. They can be captured with dog collars to become a trained attack dog.
The Marauder will occasionally summon an orange spectral Hellhound, which chases you and delivers biting damage. While more of a nuisance than a threat, damage from the Hellhound can add up quickly and distract you from the fight at hand.
Behind the scenes
The Hellhound is a monster intended to appear in Doom 64, and sadly, it didn't make it to the final cut. Its existing sculpture is that of a demonic canine with two heads, resembling the Greek mythogical Orthrus.
