I believe there are quite a few of us on here who have been through this. My Cassie came to me as a foster dog through HRI when she was 2 1/2. She had a cherry eye when she came to me and had it for quite a while. Her previous owners chose to never do anything about it. Cassie had it surgically repaired. We did not remove the gland, but tucked it under as they recommend. I had been told it can cause dry eye and other problems to remove it and tucking is better. Cassie did fine with the surgery and had no problems there after. I would recommend finding a specialist or a vet who can tack it as opposed to cutting it out. I am sorry you are going through this, and you must be very worried. Honestly, he will be fine. Try not to panic. It is very common.
