Pen VK for Pneumonia, really. Azithromycin works just fine for small Pneumonia's, the next step up for humans that I have seen used the most is IV Levaquin, but at that point, one would have a bad Pneumonia, and is admitted to the hospital.
Yes, Azithromycin is something I have had in the past a few times with our dogs. I prefer the liquid form, just easier to give.
Charlie, are you Hungry ?
