What's this brown stain on my dog's eye? Is it a tumor or just a freckle?

BROWN STAIN DOG'S EYE: TUMOR ? I took my dog to the vet last week after noticing that her conjunctiva was inflamed, basically her sclera was a little reddish. She gave me eyewash and Fradexam, the treatment consist of 4 drops a day for a week. Today while giving her daily drops I noticed a brown stain on her sclera( cf: see picture). Can you tell me if this looks like an ocular tumor to you ? The vet did the fluorescein eye stain test, nothing showed up.

It almost looks like an eye freckle. However I would follow up with your vet for an up close eye examination. A referral to an ophthalmologist may also be needed to know for sure. Just an FYI, most eye tumors in dogs are involving the iris and not the sclera (white part of the eye). Best wishes with your pet and I hope everything works out well for Lili.

    I am assuming that it is the dark brown spot in the sclera that is in question? Eyes are very hard to evaluate with a 2 dimensional picture, but it appears flat to me. This is likely a nevi, or “freckle” , however I can not rule out a tumor such as a melanoma. I would encourage you to have her evaluated by your veterinarian soon. Best of luck and thank you for using Pet Coach.
