Sweeney Todd

I took a lovely trip to the cinema last night to watch Sweeney Todd (good film!) and couldn't help but notice there was one dog in it. Now i've been pissing people off for a long time by pointing out dogs in films but a lot of the time they seem to appear for the sole reason of having to have a dog in the film! Why? I'm going to try and find out...

Anyway this dog walked past near the beginning while Anthony was sitting on a bench near a park so not that strange this time...
