Now then, today we went and exchanged the costume for a size 'medium', suitable for a cocker spaniel. We liked the wizard costume, but simply couldn't resist the pig, insert rude comments here. (We also could barely resist the doggy backpacks, but managed) She seems to like this one somewhat better, as it fits and also doesn't have leg holes. She was not thrilled about the head on top of her head, though. These costumes, by the way, are very cheap and SO worth the pleasure we got out of them. I'm willing to forgo another pleasure in order to get the laughter we got from this :)
