The #WhatTheFluffChallenge is basically a game of peek-a-boo with your dog, but some of these puppers are a little more switched on than they seem.
Dog owners taking part in the challenge hold a sheet or something similar in between them and their dog, before dropping the sheet and moving away, making it seem as though they’ve disappeared.
The dogs then ponder where their owner has got to, before being reunited with them.
But it doesn’t always go to plan. You have to get up pretty early to catch some of these pets out.
Meanwhile, others might be fooled once, but twice? No chance.
Be afraid. The dogs are learning.
