See these dogs try to stand up to cats

We all know cats and dogs can live together and get along, kind of. This video shows how even though cats are smaller, they are definitely fiercer.  In one video, a cat won't get off the dog's bed. In another, a cat won't let a dog go upstairs and chases him back down. And in another, a cat scares the dog into running into a closet.  All the videos are here.
