TL;DR: A pink fleshy lump in the corner of a dog's eye is usually "cherry eye," a prolapsed tear gland that is not typically an emergency but requires a veterinary exam to prevent long-term complications like dry eye.
What is the pink fleshy lump in the corner of my dog's eye?
A pink, fleshy mass appearing in the inner corner of your dog's eye is most commonly a prolapsed gland of the third eyelid, a condition widely known as "cherry eye." Unlike humans, dogs have a third eyelid that houses a vital tear-producing gland. When the connective tissue holding this gland in place weakens, the gland pops out, appearing as a red or pink protrusion.
Is a pink lump in my dog's eye considered a veterinary emergency?
- The urgency level for a typical cherry eye is Low; while the appearance is startling, it is generally not painful or life-threatening in its early stages.
- Because the exposed gland can become irritated or interfere with tear production, it should be examined by a veterinarian during a scheduled appointment.
- A professional evaluation is necessary to prevent long-term complications like dry eye (Keratoconjunctivitis sicca).
How does sending a photo of my dog's eye help with veterinary triage?
- A clear, well-lit photo allows a professional to confirm if the lump is consistent with a prolapsed gland.
- Images help rule out signs of more urgent issues, such as a corneal ulcer, a foreign body, or an aggressive growth.
- High-quality photos help determine if your pet needs to be seen today or if the condition can wait for the next available routine opening.
Clinical Context (Merck Veterinary Manual)
Hypertrophy, inflammation, and prolapse of the gland of the nictitating membrane (cherry eye) is common in young dogs, especially certain breeds such as American Cocker Spaniels, Beagles, Lhasa Apsos, Pekingese, and English Bulldogs. In the acute stage, the red glandular mass swells and protrudes over the leading margin of the nictitans, and there may be a mucopurulent discharge. Because the gland is a major tear gland, it should be preserved if possible; the gland should be replaced and anchored with sutures to the orbital rim, periorbital fascia, or nictitans cartilage, or covered with adjacent mucosa (envelope or pocket techniques). Partial excision should be avoided, as complete excision may predispose 30%–40% of dogs to keratoconjunctivitis sicca later in life, and surgical or medical resolution still predisposes approximately 20% of dogs to future keratoconjunctivitis sicca; therefore, these dogs should be monitored for several years after undergoing surgery.
