Why it worked
The video uses a humorous and unexpected scenario of a dog performing human-like tasks, combined with anthropomorphism through clothing and a relatable situation (a dropped item in the toilet), to create engaging and shareable content.
Summary
A chihuahua dressed in human clothes attempts to clean a knit hat that has fallen into a toilet. The dog retrieves the hat, washes it in a sink, and then dries it with a hairdryer, before a second dog, also dressed in human clothes, appears and tries to put the hat on.
