Move over Lassie – you have competition. Excitable puppy Rosie tries repeatedly to engage her playmate in some rough-and-tumble until her friend responds with a nip to the neck.
But the dog dramatically falls to the ground and plays dead with Oscar-worthy conviction.
The video of Rosie's performance has become a viral hit, being watched by hundreds of thousands of people.
The dog's acting is so convincing, some viewers have suggested that it may be an instance of canine narcolepsy, a rare but generally harmless condition which causes the animal to faint in response to high adrenaline.
