Cherry Eye in Dogs: Symptoms, Causes, Treatment, and Prevention

Cherry eye in dogs is the prolapse of a gland located in the third eyelid, appearing as a reddish, round swelling in the inner corner of the eye, and it’s considerably more common in certain breeds.

Despite its alarming appearance, cherry eye isn’t typically painful in its early stages, though the condition needs prompt treatment to protect the gland’s important role in tear production. This guide covers what causes cherry eye, its symptoms, how it’s diagnosed, how it’s treated, whether it can be prevented, and when to see a veterinarian.

This guide covers what cherry eye is, what causes it in dogs, its symptoms, how it’s diagnosed, how it’s treated, whether it can be prevented, when to see a vet, and what else people ask.

What Is Cherry Eye in Dogs?

Cherry eye is the common name for prolapse of the gland of the third eyelid, a structure located at the inner corner of a dog’s eye that normally sits unseen and contributes a meaningful portion of the eye’s tear film. When the connective tissue holding this gland in place weakens, the gland flips up and becomes visible as a round, reddish mass, which is where the condition gets its descriptive nickname. The condition can affect one or both eyes and most often appears in young dogs.

What Causes Cherry Eye in Dogs?

Cherry eye results from a weakness in the connective tissue that normally anchors the third eyelid gland in place, allowing the gland to flip outward and become visible. The exact reason this connective tissue weakens isn’t fully understood, but genetics plays a clear role, since certain breeds, including the Bulldog, Cocker Spaniel, Beagle, Shih Tzu, Lhasa Apso, and Bloodhound, show a well-documented predisposition to the condition. Cherry eye most commonly appears in dogs under two years old, suggesting a developmental component to the underlying weakness.

What Are the Symptoms of Cherry Eye in Dogs?

The defining symptom of cherry eye is a visible, round, reddish-pink mass at the inner corner of the affected eye, often appearing somewhat suddenly. The gland itself isn’t usually painful early on, though a dog may paw at the eye or show mild irritation as the exposed tissue becomes dry or irritated from exposure. Left untreated for an extended period, the exposed gland can become increasingly inflamed, swollen, and prone to drying out, which raises the risk of longer-term complications affecting tear production.

How Is Cherry Eye in Dogs Diagnosed?

Cherry eye is typically diagnosed through a straightforward visual exam, since the prolapsed gland’s appearance is distinctive and recognizable to a veterinarian. A broader eye exam helps rule out other conditions that could coexist with or mimic cherry eye, and a veterinarian also checks the overall health of the eye and surrounding tissue to plan the most appropriate treatment approach. No advanced imaging or lab testing is typically needed to confirm a cherry eye diagnosis.

How Is Cherry Eye in Dogs Treated?

Surgical repositioning of the gland, rather than removal, is the standard and strongly recommended treatment for cherry eye, since the gland plays an important role in producing tears and removing it entirely raises the long-term risk of dry eye. Several surgical techniques exist for securing the gland back into its normal position, and a veterinary ophthalmologist or experienced veterinarian can determine which approach fits a specific case best. Prompt surgical treatment generally produces good outcomes and preserves normal tear production going forward.

Can Cherry Eye in Dogs Be Prevented?

Cherry eye generally can’t be prevented in a dog with the underlying genetic predisposition for weak connective tissue in this area, since it’s a structural issue rather than something caused by an external factor an owner can control. Responsible breeders can help reduce the condition’s prevalence over generations by avoiding breeding dogs that have experienced cherry eye, particularly within predisposed breeds. For an individual affected dog, prompt treatment is the most effective way to prevent the complications that can develop if the condition goes unaddressed.

When Should You See a Vet for Cherry Eye in Dogs?

See a veterinarian promptly if you notice a reddish, round mass at the inner corner of a dog’s eye, since early treatment generally leads to better outcomes and lower risk of complications. It’s worth scheduling the visit soon rather than waiting, even though the condition isn’t usually an emergency in its early stages, since prolonged exposure of the gland raises the risk of lasting damage to tear production. A dog that’s already had cherry eye in one eye should also be watched for the same issue developing in the other eye, since the condition can affect both over time.

What Else Do People Ask About Cherry Eye in Dogs?

The questions below cover whether cherry eye is painful, whether it can go away without surgery, which dogs are most at risk, and whether cherry eye can come back after surgery.

Is cherry eye painful for dogs?

Cherry eye isn’t typically painful in its early stages, though a dog may show mild irritation or paw at the eye as the exposed gland dries out or becomes inflamed over time. Leaving the condition untreated for an extended period increases the likelihood of discomfort developing as complications set in.

Can cherry eye go away without surgery?

No, cherry eye generally doesn’t resolve on its own and requires surgical correction to reposition the gland properly. Some owners try massage or other non-surgical approaches, but these aren’t considered reliable solutions and surgery remains the standard, recommended treatment.

Which dogs are most at risk for cherry eye?

Breeds including the Bulldog, Cocker Spaniel, Beagle, Shih Tzu, Lhasa Apso, and Bloodhound show a well-documented elevated risk for cherry eye, and the condition most often appears in dogs under two years old. Any breed can potentially develop cherry eye, but these breeds account for a disproportionate share of diagnosed cases.

Can cherry eye come back after surgery?

Yes, cherry eye can recur after surgery in some dogs, though modern surgical techniques that reposition rather than remove the gland have generally improved success rates considerably. A veterinarian can discuss the specific recurrence risk associated with the surgical technique used for an individual dog.
