The #whatthefluffchallenge is taking the internet by storm. In the challenge, pet owners ‘disappear’ behind a blanket – much to the bemusement and of their pets. In this video, Elf the dog is amazed when his owner Seba ‘disappears’.The confused canine bounces around, barking and looking at the location where his owner had been standing. Before long, Seba returned to reassure her pet. Seba told Storyful that she created the video to have a little fun with both Elf and Seba’s four-year-old son. Credit: elf_the_pirate via Storyful
