Here's the another shot.

and now the other side

and one other note, he's been wearing an e-collar most of the time so he doesn't irritate the wounds.

The site below discusses exactly what you're seeing and what my suspicions were.....something to do with the sinus or teeth.
I'd get a 3rd opinion since the antibiotics don't appear to be having an effect.

Also, neosporin isn't really an antibiotic so if that's all he's been getting then it's no surprise he's not better. The wound is already open, so it's probably draining on it's own.....as much as it can.

Poor guy........3 weeks in a collar? : (
Is the collar really needed? My guess is that it's only irritating the site more.

Thank for that link, Ann. That does sounds exactly like what I saw on the dog, too . Could there be a problem underneath that would only show up on Xrays (on both sides)? Both vets did a visual of his teeth. I will ask my friend in the morning if the regular vet knows about the second spot yet. I get frustrated when I can come on this forum and get a probable dx so quickly and the treating doctors have the animals suffering for these long periods of time. At least he doesn't seem in pain and he's prancing around like a pup.

She put the neosporin on in addition to the rx antibiotics just to try to help it along.

Yes, she was putting on the collar as much as possible to try to keep him from pawing at it so it would heal. It's far enough down where it's not hitting his face. But, LOL, he likes to wear it! Funny guy!

Yes, x-rays would be needed to see what's happening in that area of the skull.
A problem with the root or sinus would be within the bone and not something a vet will see with a visual exam.

Great. Thank you very much. I'm going to pass all this info along to my friend so she can get her little doggie taken care of properly.

ditto on dental problems likely (infected carnasal tooth roots most likely)

I just wanted to give an update about the dog. He did need to have 2 teeth removed. He's doing much, much better and the infection on his face is finally starting to clear up. He's got his follow-up appointment next week but all looks well!
