Sophie often sees old Mr Jenkins walking his Labrador puppy, Buttons, and wishes she could have a dog of her own just like her. Buttons loves the outdoors and is always running off even though she knows she shouldn`t. Then one day, Sophie sees Buttons climb out of the window. She thinks she`s running away again, but Buttons isn`t playing around this time – something at home is very wrong, but how can she let Sophie know…?
