The races are on sand and dirt, and the dogs pull a wheeled rig instead of a sled. The Downeys start training the dogs at five months old. The animals have to learn that gee means right and haw means left. Sled dogs are harnessed to the sled, but the driver has no reins the dogs have to follow voice commands. You could take the best athlete in the world, but if he s not good with dogs or can t read them, he won t work, says Rob Downey.
Dogs have bad days, like people.
You have to be able to read them. Your clothes don't talk to you now, but someday they may. With the help of computers and special high-tech fabrics, smart clothes could send and receive information and adjust to give you what you need at any moment. Scientists think they may be able to create fabric that, like a chameleon, will change color to match your surroundings. Shoes could measure how far you'd walked, or change to fit your feet in different ways for different sports.
