My dog's iris is spreading into the white of her eye. Is it serious?

Updated On September 23rd, 2025

Pet's info: Dog | Chihuahua | Female | unspayed | 7 years and 5 months old | 7 lbs

I’ve noticed this right now as I was laying with my dog but her iris is leaking into her sclera? I don’t know if leaking is the right word to use but its really concerning me and I just want to know if it need immediate attention.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Precious! I would have her seen by your Vet and then have her referred to an ophthalmologist. I am worried about an iris melanoma or a cyst. I do think you should have her seen soon. I wish you the best!
