It's hard to believe that the dog is growing stronger today, capable of doing a lot of personal behavior that people can't do, seeing as the dog can stand on a roller ball and maintain balance.
The dog can stand up, must have gone through a lot of training, see how powerful it is if it jumps at once, but is this personal act of the dog interested in itself or does the owner intend to do it?
The dog is very cool on the upper side of the ball, and if the ball goes, the ball goes, and if the ball slows down, it slows down, it's strong, and the dog is fine, and he likes to play on the ball.
But this ball is big. Is it professional for dogs? If one person sits on it, it is believed that it is not easy to be a dog, and the human balance is sometimes worse than a dog.
It's hard to believe that a dog can do that, but it's more convincing than a dog, and only admires the dog.
