My dog's eye spot is growing. Is it melanoma? What should I do?

Hello, I was wondering if pigmentation on my dogs eye would grow over time, or if they would stay the same size? My dog has a brown spot on her eye and the vet thought it was a pigmentation but it's already doubled in size in two months and now I'm worried it's a melanoma! Thoughts?? How do they treat a melanoma? I read they are more likely benign.

Thank you for contacting PetCoach with your question about Ellie. The pigmentation can grow over time. I will put a link below to an article as to what this could be. If this is pigmentary keratitis, the underlying cause needs to be diagnosed so it can be treated correctly. Even if this was a melanoma, yes they are usually benign in dogs. In fact, 80% of them are benign. If it was melanoma, it could be destroyed with a laser since it's small. Have her see a veterinary ophthalmologist before getting too worried about it. Best of luck. https://www.northwestanimaleye.com/pigmentary-keratitis.pml
