Why it worked
The video leverages a relatable and humorous challenge involving a pet, which is a common driver of engagement on social media. The dog's varied reactions and the "side eye" add an element of surprise and personality, making the content shareable and entertaining.
Summary
A woman and a man take turns kissing their Rottweiler dog to see who the dog looks at first. They do this for multiple rounds, with the dog reacting differently each time, sometimes looking at the woman, sometimes at the man, and sometimes appearing to give a "side eye."
