Poor Chachi! This same thing happened to Ezra (my neighbor shi tzu) about a month ago. The vet said it was an allergy presenting itself through the skin. She was on medicine and had a special wash for it for a few days. She had bitten and scratched at it so bad it was open too. I hope that is all it is and he will be back to normal again real soon!
