Sad dog

As I put the harness on Harry, I noticed that he kept licking his leg. On closer inspection I discovered a huge deep gash. I dropped everything and raced him off to the vet. Two hours later I have a very drugged up dog with numerous stitches. I don't know how he manged to get cut... but it was very sharp and also went into some muscle.
Sorry for the out of focus image... I only managed a few snaps before it got too dark to take any more.
