Buttons the Runaway Puppy

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...?
