Glad to hear the eye was healing! I'm thinking because this was a puppy and not an older dog the healing was easier. Yes the eyes will look worse before they get better when healing from an ulcer. I also was instructed to use only an ointment for lubrication and no antibiotic. The antibiotics were making my dog's eye worse. He squinted terribly from them. Once I used only the Puralube after the corneal grid, the eye turned the corner. Let us know when the pup's eye is all back to normal!
