My cousin, Ron has a dog. It is an intelligent and beautiful pet with a short tail and big brown eyes. Its name (be) is Rex and it likes eating meat. Although Rex barks when strange guests visit, it never bites anyone; To be honest, Rex is very friendly. It does not like .eating fruits, such as apple, orange, banana, or grape, but it often plays with them. If the weather becomes bad, Rex just sleeps in his cage all day. Ron plays with his dog every day after school. Because there are many people on the road, Ron does not letthe dog run into the road. Ron often takes . Rex to a large field in the park to enjoy the peace there. Rex is sometimes naughty, but Ron loves it very much.
