Cat Leaves It's Mark

Our Dog got a bit too close to one of our Cats today and he left his mark on her nose - If you look carefully you can see the discarded cat claw sheath embedded in the Dogs nose.

I assure you it wasn't really dug into the skin really (just the hair) and it didn't appear to hurt her either - I just thought it was so funny when I looked and thought, 'what's that'?
