A huge ass dog that loves to take up all the room on your couches and will sit on the couch with just their butt. They also slobber a lot and will shake their head and fling it on your ceilings and walls. The English mastiff slept on kings and queens a while back to keep them warm too.

Person 1: oh, he’s an English mastiff.
Person 2: holy shit ~runs for life~
