Cherry Eye in Dogs: Causes and Treatment

Cherry eye is a common condition among dogs that occurs when part of a dog’s eyelid—the “third eyelid” tucked in the inner corner of the eye—moves from its normal position and creates a red, round bump that resembles a cherry. It requires treatment from a veterinarian. 

Cherry eye in dogs may develop suddenly or gradually, and it can also be present at birth. It’s most common in dogs younger than 2 years old because their eye ligaments are weaker.  

Your dog might not be bothered by a cherry eye at first. However, the exposed eyelid can become dry and irritated over time, leading to discomfort and secondary complications, such as eye infections, dry eye, and corneal ulcers. These can all lead to vision loss if untreated.  

The cause of cherry eye in dogs is unknown. However, certain breeds—including Bulldogs, Boston Terriers, and Cocker Spaniels—are predisposed to cherry eye, and it’s thought that a dog’s genetics may play a role because it commonly occurs in dogs with weaker eye ligaments that allow the eyelid to move.  

Other potential causes of cherry eye include: 

• Traumatic eye injuries, such as bumping into a hard object  
• Chronic eye inflammation, often resulting from an infection or allergies 
• Weak eye ligaments that are not fully developed due to young age  

Cherry eye in dogs is not a veterinary emergency, but it does require timely veterinary care. Without treatment, it can lead to complications that may affect your dog’s long-term eye health and vision.  

In most cases, a veterinarian can diagnose cherry eye by examining the red swelling in your dog’s eye.  

To check for underlying issues or secondary complications, your vet may also perform: 

• A complete eye exam to check for abnormalities, such as inflammation 
• A Schirmer tear test to check for eye dryness  
• A fluorescein stain to check for scratches or ulcers on the eye 

Surgery is the most effective treatment for cherry eye in dogs. The procedure repositions the prolapsed third eyelid gland back to its normal location. 

After surgery, dogs are often prescribed topical eye medications, such as Terramycin, to help prevent infection and reduce inflammation. 

Before surgery, your veterinarian will perform a physical exam and may recommend blood work and a urinalysis. You can discuss any concerns about anesthesia with your vet.  

Some dogs—particularly those with chronic health conditions like heart disease—may not be good candidates for surgery. In these cases, medical management may be recommended, including:  

• Topical anti-inflammatories, such as dexamethasone ophthalmic solution, to reduce swelling and inflammation 

• Artificial tear products, like Optixcare Dog & Cat Eye Lube Plus Lubricating Gel, to keep the eye moist and prevent the risk of dry eye 

Medical management does not cure cherry eye. These treatments are used long-term to manage inflammation and keep your dog comfortable if surgery is not possible.  

After surgery, your dog’s eye may appear red or cloudy, and their vision may be blurry as they recover. These changes are typically short-term and improve as healing progresses.  

Most dogs recover within about two weeks. During this time, you can support healing at home by: 

• Providing a quiet, private space to rest: Set up a calm area with a comfortable blanket and cozy bed. 

• Limiting activity: Preventing running, jumping, or rough play to keep eye pressure regulated and protect stitches.  
• Using a recovery cone: This prevents your dog from scratching their eye. 

• Offering a secure resting space if needed: A crate with a pad can help keep your dog calm and separated from other pets.   

• Providing mental enrichment: Puzzle toys can help keep their minds engaged and stave off boredom.   

Although rare, cherry eye can recur following surgery, especially in breeds predisposed to it. In that case, it will need to be reevaluated by a vet.   

What is cherry eye in puppies?  

Cherry eye in puppies is a condition in which the gland of the third eyelid prolapses (slips out of place), creating a red, swollen bump in the inner corner of the eye. It’s the same condition seen in adult dogs, but puppies are more likely to develop it because the connective tissues supporting the third eyelid gland are weaker at a young age. 

What is a nictitating membrane in dogs?  

The nictitating membrane—also referred to as the “third eyelid”—is a small, pink part in the inner corner of a dog’s eye. Its role is mostly to lubricate and protect the eye and produce tears. 

Can cherry eye correct itself in dogs?  

No. Cherry eye does not correct itself in dogs, and canines with cherry eye always need to see a veterinarian.  

How much does it cost to fix a cherry eye on a dog?  

The cost of cherry eye surgery varies based on location, the veterinary practice, and whether a board-certified veterinary ophthalmologist performs the procedure. In general, you should expect to pay at least a few hundred dollars, but costs may go into the thousands.   

Can a dog live comfortably with cherry eye?   

Sometimes. Dogs can occasionally live comfortably with cherry eye, but it’s still best to receive treatment to avoid future vision issues. If surgery is not possible, topical medications are necessary long-term to reduce inflammation and keep the eye well-lubricated. Always see a vet to determine the best course of treatment.  

How can you prevent cherry eye in dogs?  

Cherry eye in dogs cannot be prevented. The condition is believed to have a genetic component, and certain breeds are more predisposed than others.
