Allie is now9 years old. She will be 10 in October. She has an ulcer in her right eye. We tried tobramycin drops the first two weeks. There was no change. We then went to plasma and ofloxacin drops and it’s been two weeks with no change. Sometimes it actually seems like the drops make it worse. The vet did something where she scraped it the last time we were there and still no change. I’m very concerned. I don’t know what to do. Should we try a different doctor? She said boxers take a long time to heal.
