Cherry Eye in Dogs: Causes and Treatment
A cherry-red lump in the corner of the eye looks alarming, but it is a recognized and treatable condition.
What it is
Dogs have a third eyelid, a membrane in the inner corner of the eye. A tear-producing gland attached to it can slip out of position and bulge, becoming visible as a red mass. Weak connective tissue is thought to play a role.
Who gets it
Young dogs, often under two years old, are most affected. Breeds with higher risk include bulldogs, Boston terriers, beagles, cocker spaniels, Lhasa apsos, Shih Tzus and some mastiffs. See health issues in flat-faced breeds.
Signs
- Red or pink swelling in the corner of the eye
- Excess tearing or discharge
- Rubbing the eye
- Redness of the surrounding tissue
- Dry-looking eye over time
It can affect one or both eyes, and the second eye may follow later.
Why treatment matters
An exposed gland dries out and becomes irritated, inflamed or infected. The cornea may be harmed by rubbing. The gland also supplies a large share of the eye's tears, so protecting it is important. See dry eye in dogs.
Treatment
- Veterinary exam to confirm the diagnosis and check the eye surface.
- Medication such as anti-inflammatory drops may be used before surgery.
- Surgical repositioning: the gland is tucked back and anchored in place using one of several techniques.
- Aftercare: a cone, eye drops and rechecks.
Removal of the gland is no longer commonly recommended unless it is severely damaged, because of the risk of chronic dry eye.
Success and recurrence
Most dogs do well after repositioning, but the gland can prolapse again, sometimes needing another procedure. Your vet or a veterinary ophthalmologist can discuss options.
At home
- Prevent rubbing with a cone.
- Clean discharge gently. See how to clean dog eyes safely.
- Give medications as prescribed.
- Do not attempt to push the gland back yourself, since you can cause injury.
Related conditions
Dogs with cherry eye may also have other eye conditions. See dog conjunctivitis and why is my dog's eye red or discharging. Regular eye checks help detect problems early.
Prevention
There is no proven way to prevent cherry eye, since anatomy plays a role. Responsible breeders consider eye health. Early recognition and treatment protect the eye.
When to call your vet
Contact your vet if you see a red bulge, squinting, cloudy eye, heavy discharge or pain. Early care limits damage.
Common mistakes
- Waiting to see if it resolves.
- Massaging it at home.
- Requesting gland removal without discussing risks.
- Skipping aftercare.
Troubleshooting
- The bulge comes and goes: schedule an exam, since it can worsen.
- The eye looks dry after surgery: tell your vet immediately.
- My dog rubs his eye: use a cone and call your vet.
A simple plan
- See your vet.
- Discuss repositioning.
- Protect the eye after surgery.
- Recheck as advised.
Real-life examples
A young bulldog has a red lump in his eye, and surgery repositions the gland. A beagle has an intermittent bulge that finally stays out and gets treated. A spaniel develops cherry eye in the second eye months later and is treated early. Early care helps.
Staying vigilant
Check eyes regularly, especially in breeds at risk. Quick action prevents complications.
Choosing a surgeon
Gland repositioning techniques vary, and skill matters. Ask your vet whether they routinely perform the procedure or whether referral to a veterinary ophthalmologist makes sense, especially for recurrences. Ask about the technique they use, what the recovery looks like and how recurrence is handled.
After surgery at home
Keep the cone on until your vet says it is safe, since rubbing can undo the repair. Give drops on schedule, keep the eye clean and limit rough play. Report swelling, redness or discharge promptly.
The takeaway
Cherry eye is a treatable gland prolapse. See a vet early and aim to preserve the gland.
Frequently asked questions
Is cherry eye painful?
It can be uncomfortable and cause irritation and rubbing.
Can it go back by itself?
Sometimes it pops in and out, but it often needs treatment.
Will surgery fix it?
Replacement surgery works for many dogs, though recurrence can happen.
Why not remove the gland?
The gland produces tears, and removal can cause dry eye.
