Penicillin is kind of a cure all on the farm. I used it on one of my Mom's dogs not long ago. The area surrounding the dog's eye was red and swollen and the eye was nearly swelled shut. It was late at night and I don't exactly trust the ER Vet so, I gave her a shot of penicillin put some ointment in her eye and on the area around her eye. The next morning the swelling had gone down considerably so I gave her another shot. I ended up saving a trip to the Vet.
