I am very very sorry to hear this. I have been dealing with this as well for months. Zulu doesn't appear to have a broken jaw, but he has had a terrible infection that we have been unable to get a handle on, even with proper meds. I am trying to get roaches down him now because of the high protein. He's hungry but isn't eating these days. I am determined to figure out what is wrong, but the vet and I are scratching our heads. He is older. I don't know how much this plays a part in it. I will post a photo of his mouth, which has a hard goldish-brown ring around his teeth. It's hard to get in there to see much of what is going on, but the same color gunk comes out of those two bumps on his head. The vet tried to clean them out but they keep filling up -- one side in particular. I'm doing everything I can for the little guy. I adore him. Here's a photo. It's the best one I have. Any advice/suggestions are appreciated. I am have been doing what you all suggest.
