　　In the United States, there are many important animals. They help us in a wide range of ways from food production to scientific research. An animal that is not only helpful to us but close to us emotionally is the dog. That is why I feel that dog are the most important animals in my country.
　　Dogs provide a very important chance to learn or maintain social skills. Children who have dogs learn responsibility while caring for them. Dogs also help older people. The elderly often feel lonely as they get older and have fewer living friends and relatives. They are able to maintain a positive outlook and to feel needed because they are caring for a dog that needs them.
　　In addition to social benefits, dogs also provide some very important assistance. Seeing-eye dogs help the blinding live fulfilling, fully mobile lives. Dogs that act as shepherds on small farms are also very helpful. Lost animals means lost money for farmers, and that can mean going out of business. Police dogs can find illegal drugs, catch criminals, and protect their handlers. Dogs’ intelligence and desire to please people made them ideal for all kinds of work..
　　Finally, dogs can save lives. Dogs have been known to find lost children .In extremely cold conditions, they have provided them with life-saving warmth. Dogs have alerted people to fires and other dangers. And we cannot forget guard dogs, which save many owners’ lives and property each year by scaring off potential burglars.
　　Again, there are useful animals in the United States. In terms of the numerous ways in which they can be helpful, however, I believe the dog is the most significant.
