Thanks for your response. And yeah the vet mentioned that in shepherds and labs it is sometimes seen under a year of age. I think his is likely a Uveal melanoma and not limbal, we will find out more when we go back to the ophthalmologist in March. We will likely be trying laser therapy first to shrink the mass, and if that doesn't work we may progress to an iridectomy. I asked her about the ONCEPT vaccine and she said it would not be used in a case like this since the chances of it being malignant to the rest of the body are super low. Do you remember what made them more concerned in your dogs case about it spreading? From everything I have heard even if left untreated in the eye it is still super unlikely to spread anywhere else.
