A pet dog named Dong-dongi lashing out at a vacuum cleaner is going viral. The moment the video dropped, it drew a flood of comments and attention.
In a clip released on the KBS Enter YouTube channel on March 23, 2026, dog trainer Min-hyeok Choi appears and demonstrates how to neutralize Dong-dongi's aggression.
In the video, Dong-dongi keeps barking at the vacuum and shows aggressive behavior. Watching closely, trainer Min-hyeok Choi uses neck control to imprint real hierarchy and conducts training to dial down the aggression.
'Dogs Are Incredible' has previously covered similar training methods, drawing major interest from dog owners. Dong-dongi's case, in particular, highlights dogs' unusual reactions to vacuum cleaners. According to the production team, they also looked into how dogs perceive vacuums during filming.
