Last yearLinda and Steve visited their grandfather. Helived in a small house in Cambridge. The weather was fine and the children had a lot of fun. One day they saw a little dog in the street. The children took the dog home and called it Ron. Ron was very kind and clever. They played together every day.

Autumn came and the children went back to London. They couldn’t take Ron with them to their little flat, so Ron stayed with the grandpa. The children often thought about Ron and wanted to visit it. One morning Linda looked out the window and saw Ron. The dog found them and came with a present. Ron had Steve’s old shoes in the mouth!
