Here is a video of a boston terrier dog named Doc. In this video, Doc is doing the bucking bronco when he is playing with his Chuck-it ball.
This is what Doc’s owner says about it : “Our Boston Terrier Doc gets so happy sometimes that he does his impression of a bucking bronco. Doc loves (LOVES!) chuck-it balls and almost every time he is playing with one of his chuck-its he will do the bucking bronco.”
