This is the amusing moment a tiny lap dog kept barking at another pooch hanging out of a car window in Myanmar.

Footage shows the aggressive pet named Key Key riding a car and yapping frantically after seeing the larger dog enjoying the breeze through a passing SUV's open window.

Key Key then clambers onto the dashboard while continuing to snarl at his rival, which simply keeps its cool as it stared at the smaller animal. It later retreats into the backseat, apparently deeming Key Key unworthy of its notice.

Furious Key Key is filmed continuing his verbal assault until the two vehicles finally pass each other by on the road.

The footage was filmed on July 30.
