Set in a post-apocalyptic world where violence, crime, genetic manipulation and other scientific experiments have become common, the story focuses on four main characters who, through a series of coincidences, meet as they search for a way "below", looking for answers to their individual pasts. The series is serious eye-candy, with alot of guns and cliché characters, but is very entertaining.
Originally the series started as a manga 'Dogs: Stray Dogs Howling in the Dark' (グッドドッグ・ステイ?): a oneshot that was succeeded by Dogs: Bullets & Carnage. Stray Dogs Howling in the Dark now serves as a prequel to the manga series Dogs: Bullets & Carnage, and has been adapted into an OVA.

A really nice OVA even if you haven't read any of the manga
