Border Collies Are The Smartest Breed Of Dogs In The World… And Nana Just Proved It.
Border Collies are known for their extremely high intelligence, unparalleled energy levels, and quick reflexes. Nana the Border Collie has been blessed with all three.
Watching the video, it looks like Nana is playing a game - that's because in a way, she is. Her owner teaches her these tricks using positive reinforcement, which means that every time she gets it right, she gets a treat. With enough practice, Nana can do it all, including backwards walking, blowing bubbles, pulling a blanket over her head, and walking on her two front paws. I guess you can teach an old dog new tricks.
