Wow, I am hoping kitty's jaw isn't fractured. Was it a stray dog or was it someone's dog who attacked him? Did your cat get into the dog's backyard? Have you taken your cat to the vet yet? I hope you have an appointment by now.
I hope your cat is okay? Please let us know!
If this were MY cat and was in this kind of condition.....I wouldn't wait. I don't understand why you're waiting. The poster above that mentioned the dog's owner should pay is right!! That dog should have been leashed, it's the laws in many states.
Do you know who owned the dog? The dog owner should pay for your vet bill.
