I found this forum while trying to research my cocker spaniel's health issues. I am Debbie and have had cockers for about 24 years. We adopted our 6 year old Peanut from a shelter, and were told he was a Merle and because of his eyes, the breeder relinquished him. He has 2 pupils in each eye, and one eye does not have an iris all the way around the pupil. One eye is blue, the other brown. I can't really tell the difference between Merle and Roan....I was hoping someone here was more of an expert. The vet now thinks he has exocrine pancreatic insufficiency. Has anyone else had this issue? It's hard to find anything online about this.
