Cream crackered

He's getting his revenge this evening for me wearing him out this morning (made him go runnies instead of walkies) now he's in and out in and out, unable or unwilling to settle in either the kitchen or the garden. This isn't a problem in the warmer months, when I don't mind the back door flapping open but when it's only 6C and the daft beast still hasn't learnt to shut the door behind him it's rather annoying.
