swollen eye

Have you suddenly noticed a red mass in the corner of your young dog’s eye? Are you concerned that there is a tumor in the corner of the eye when just a day ago everything looked normal? You could be dealing with a common problem in young dogs and puppies, especially in the cocker spaniel, commonly known as hyperplasia of the nictitans gland, “cherry eye”, or prolapse of the glands of the third eyelid.
