Hell hounds are big dog-like creatures, but to mortals they only look like a really big normal dog, like a black poodle maybe. They are pets to Hades, but most of them are evil and their essences are from Tartarus.
You, your friends, souls, whatever they can get their paws on really.
Wild, crazy, and playful.
Tips for demigodsEdit
Absoloutly do not throw knifes at Hell Hounds.They get really pissed when you do that. Imagine the reaction of taking your dog's toy away. Be careful of their teeth.
