Hi, poor baby. Cherry eye isn't painful for them, but it can cause dry eye which is irritating, plus if its big, it could affect his vision. Is this picture of the cherry eye before or after surgery? If this is after surgery, it still loos quite big, and I would say you definetely want to find another vet, and get a second opinion. Your current vet doesn't seem like he has much compassion. Was the cherry eye sewn back in? You have two options, you could have it tacked back in, or have it removed entirely. When the gland is removed, it can sometimes cause a dry eye which would need daily eye drops, when it is tacked in, it can sometimes pop back out, there is no guarantee, but also has good success. There is no right or wrong method, but you should be able to ask your vet which method they use, and do your own research, then make your decision. My female Blossom developed cherry eye when she was 5 months old, and we had it repaired when she was 7 months old, and we spayed her at the same time, to avoid putting her under anesthetic twice. We opted to have it sewn in, and the vet did a really awesome job, we are very happy with the results, and you would never know she had anything done to her eyes. We used Refresh eye drops to keep the eye moist until she had the surgery, you can buy them over the counter at any drugstore. If they are safe for human eyes, they are also safe for dogs eyes, and are much less expensive than what you would pay for them at the vet. Good luck, and keep us posted on how he's doing.
