Blog What Is Cherry Eye in Dogs?
Cherry Eye is a condition where a dog’s third eyelid gland slips out of place, creating a red or pink swollen bulge in the corner of the eye. While it may look alarming, Cherry Eye is a fairly common condition, especially in puppies and young dogs under the age of two. However, it can also develop later in life.
Dogs actually have three eyelids — an upper eyelid, a lower eyelid, and a third eyelid, also known as the nictitating membrane. This third eyelid helps protect the eye and produces a significant portion of your dog’s tears. When the connective tissue holding this gland in place becomes weak, the gland can prolapse or “pop out,” resulting in Cherry Eye.
Although the exact cause is not fully understood, genetics and weakened connective tissue are believed to play a major role.
Signs of Cherry Eye
Cherry Eye is usually easy to recognize. Common symptoms include:
- A red or pink swollen mass in the inner corner of the eye
- Eye irritation or inflammation
- Excessive tearing or discharge
- Pawing or scratching at the eye
- Squinting or discomfort
Some dogs may not seem bothered at first, while others become irritated quickly. Scratching or rubbing the eye can worsen inflammation and increase the risk of complications.
Why Prompt Treatment Matters
While Cherry Eye is not typically an emergency, it should always be evaluated by a veterinarian. If left untreated, the exposed gland can become irritated or damaged, potentially leading to long-term eye issues such as chronic dry eye (keratoconjunctivitis sicca).
Treatment options vary depending on the severity of the condition. In some mild cases, anti-inflammatory medications may help temporarily, but surgery is often recommended to reposition and preserve the gland. Removing the gland entirely is generally avoided because it plays an important role in tear production.
Early treatment can help protect your dog’s vision and prevent future discomfort.
Breeds More Prone to Cherry Eye
Certain breeds are genetically more likely to develop Cherry Eye, including:
- Bulldog
- Bull Terrier
- Boston Terrier
- Bloodhound
- Beagle
- Cocker Spaniel
- Lhasa Apso
- Saint Bernard
- Shar-Pei
If you own one of these breeds, keeping an eye on changes in eye appearance can help catch the condition early.
Caring for Your Dog’s Eye Health
Routine wellness checks and paying attention to changes in your dog’s eyes can go a long way in preventing more serious issues. If you notice redness, swelling, discharge, or signs of discomfort, contact your veterinarian for guidance.
