Who's the pig?

Peri has an obsession with Fizzy's food (which looks highly unappetising) and whenever we bring her out of her hutch he instantly has his nose in her bowl. She seems completely unfazed by him (if anything he's wary of her!), but I like the fact that she looks completely bewildered by and rather indignant at his greed. I couldn't believe how quickly he was eating - I couldn't get a picture with both of them in focus and looking the right way at the same time! It's a challenge photographing a black dog at the best of times, but next to impossible when he's next to a light-coloured guinea pig and focussed solely on eating as much of her food as possible before it is taken away from him!
