Animals do many useful and entertaining jobs. (38) Dogs are particularly valuable in guiding the blind (a trained dog can learn never to cross a busy street when cars are coming, even if his master commands him to do so), protecting property, finding lost people, and hunting criminals. Horses are used in guarding herds, carrying men in lands where there are no roads, and helping farmers plow fields. Pigeons have long been used to carry message. 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.
The first thing a dog is taught is to obey. It should not take too long for him to learn commands. Simple orders, such as "sit, lie down, stay there, come here" can even be taught by a child.
Training a dog to be a watchdog often produces unexpected results. Some dogs quickly learn the difference between unwanted people and friends. This is because their masters welcome friends and invite them into their houses. However, some dogs will always attack the postmen who come to deliver letters. One explanation for this behavior is that, although the postman comes to the house frequently, he never enters the house. Therefore, the dog thinks the postman is someone who is not wanted, but keeps coming back anyway.
Masters of dogs who attack postmen can easily show the dogs that the postman is a friend and the dog does not need to treat him as an unwanted person. A dog is quite ready to do what his master wishes. And a dog is always happy when he is praised for proper understanding.
Dogs who accompany blind people must learn______.
