Dog owners play magic tricks on their dogs in #WhatTheFluffChallenge

A game of peek-a-boo with man’s best friend is taking over the internet.

The #whatthefluff challenge is a doggy disappearing act where owners trick their four-legged friends by disappearing behind a blanket, leading to some hilarious videos.

Reactions from some very confused dogs are all over social media feeds. The hashtag has been used over 11,000 times on Instagram alone. Here are some of our favorites.
