Nio loves running. He's constantly challenging other dogs to run with him. It makes him happy. When he meets a dog that can match his speed and stamina, pictures like this one are easy to make. Just point the camera and shoot as many times as you can.
This dalmation for instance, who is just over 5 months old, was the kind of dog Nio likes. He would go on forever. When Nio stopped, the dalmation would challenge him. When the dalmation stopped, Nio kept on going. They were running with eachother for at least 15 minutes.
