Does my dog's healing eye ulcer always need a stain check?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 1 year and 4 months old | 10 lbs

When I took my dog to the vet for his follow up for his eye ulcer the vet said it was healing fine. He did this without doing any stains. Is the stain needed to determine if the ulcer is still there? The vet mentioned that it was used the first time to see the depth of the ulcer and that by simply looking at my dog’s eye he could see the ulcer was getting better

He is right. There is no need to do another stain, if you know where the ulcer was and how severe it was. You can see whether it is healing, or not without a stain. Only sometimes when there are multiple injuries, or scratches on the cornea do we need to repeat a stain. But ulcers are a pretty obvious lesion and easily assessed, so a new stain is not necessary every time. Your vet may want to do another stain once the ulcer appears healed, in order to verify that there is no more defect.
