Animals perform many useful and entertaining jobs. Dogs are particularly valuable in guiding the blind, protecting property, finding lost people, and hunting down criminals. Horses are used in guarding herds; carrying men in lands where there are no roads, and helping farmers work their land. Pigeons have long been used to carry messages. Wild animals from the jungles, forests and seas are very popular performers in circuses and movies. People realize that, although animals may not have the same intelligence as human beings, they are smart enough to learn certain things.
Dogs are extremely useful as companions for blind people. When a dog has been properly trained, he will always lead his blind master in the right direction and keep him out of danger. For example, seeing-eye dogs learn never to cross a busy road when cars are coming, even if their masters command them to do so.
Horses are also able to learn many things too. Horses that are used for guard or police duty must learn never to be frightened of noises, traffic, and other disturbance. Racing horses are able to run much faster than other horses, but they are also quite high strung. Therefore, it is necessary for people who train them to be very patient and understanding.
Pigeons have a natural instinct to return home, even if they are very far away and the trip is hard or dangerous. Men utilize this homing instinct to send messages on small pieces of paper that are fastened to the pigeon's back or legs. In wartime, pigeons have been known to fly as fast as 75 miles an hour and to cover distances of 500 to 600 miles. These homing pigeons begin their training when they are about four weeks old. After a few weeks they can begin flying and carrying messages. If all goes well, their flying career lasts about four years.
Animals can learn to do many things that, while not necessarily useful, are very amusing to watch. In circuses, animals are taught to do the tricks that are most compatible with their physical and temperamental make-up. Lions and tigers can be taught to leap and spring gracefully when told to do so, or to stay in place on command. Elephants learn to walk in line, to stand on their hind legs, to lie on their sides, and to stand on their head. They can also learn to dance.
