Thanks for updating. I sure hope the antibiotics will get him through this. You can use VetRX too if he seems to be having any difficulity breathing it is similar to vicks rub for us humans. but it's liquid so I swipe it across their nares with a cotton ball so it doesn't actually run down into their nares. Hopefully, by the end of the weekend you'll see a change for the better. 
He knew what was coming though and would fight to keep his mouth closed when I'd open it. I felt bad cause it exhausted him and he looked so weak after. He ended up passing away this morning :-(
