Border Collies are considered to be the most intelligent dog breed. Because they are so smart, they are very easy to train, but there’s nothing simple about the trick you’re about to see. Border collies Ace (black and white) and Holly (red and white) are less than 3 years old, but they were able to learn one of the most incredible tricks I have ever seen. In the video, both dogs display their incredible ability to do a balancing act with their owner and trainer Dai Aoki. As far as animal video go, this one is definitely worth the watch. Wow!
