Hound [Backrooms]

3D Model

Official wiki:

The name “Hound” comes from the dog-like nature of these Entities, crawling on all fours and mauling anyone that provokes them. Hounds are humanoids with strange biology, with arms and legs that are built for travel on all fours. They are highly aggressive, and are made aggressive when they see someone in an aggressive state, but can be intimidated by direct eye contact.
