Dog Breeds Most at Risk for Cherry Eye

Every dog has three eyelids per eye, including a third eyelid known as the nictitating membrane. Although this third lid is usually hidden, it serves a crucial protective function. When a dog's eye gets injured or infected, this eyelid can become swollen and visible, often making the eye look irritated and watery.

Understanding the Third Eyelid's Role

The third eyelid acts as a vital shield, especially for dogs that frequently run through brushy terrain or rugged landscapes. It defends the cornea from foreign particles and keeps the eye properly lubricated. The tissue within this membrane also supports healing and guards against infections when the eye is compromised.

How the Third Eyelid Protects & What Exactly is Cherry Eye?

When a dog experiences eye trauma or infection, the third eyelid moves to cover the affected area, forming a natural barrier to further damage. Cherry Eye occurs when the gland inside this third eyelid prolapses, or slips out of its normal position, creating a noticeable red or pink fleshy lump at the inner corner of the eye.

While any dog can develop Cherry Eye, certain breeds are genetically more susceptible due to their facial shape and eye prominence. Usually, it starts in one eye and can eventually affect both.

According to American veterinary experts and studies, the breeds most likely to develop Cherry Eye tend to be flat-faced (brachycephalic) dogs and some crosses. These include:

• Cocker Spaniel puppies
• Beagle puppies
• Boston Terrier puppies
• English Bulldog puppies
• Lhasa Apso puppies
• Pekingese puppies
• Bloodhound puppies
• Mastiff puppies
• Saint Bernard puppies
• Chinese Shar-Pei puppies
• Shih Tzu puppies

As an example, in the United States, English Bulldogs and Boston Terriers are popular pets but are notably predisposed to this condition. Also, breeds like the American Cocker Spaniel and Beagle, commonly found in American households, are among the vulnerable breeds.

Recognizing Symptoms, Treatment Options, and Prevention

Cherry Eye is impossible to prevent outright due to its genetic nature, but early detection and prompt action can significantly improve outcomes. It often appears in puppies and young dogs under one year, visible as a bright red, swollen mass at the inner corner of the eye. If left untreated, the condition may cause secondary eye problems such as dry eye syndrome, conjunctivitis, or corneal ulcers.

Veterinarians in the US strongly advise against removing the gland as this can cause chronic dry eye by eliminating tear production. The preferred approach is a surgical procedure to reposition the gland, typically yielding positive results, especially when done early. In very early stages, anti-inflammatory eye drops may be prescribed to reduce swelling temporarily.

Dog owners should reach out to their veterinarian as soon as Cherry Eye signs are noticed to avoid discomfort and serious eye complications.

Final Thoughts

The third eyelid is an essential eye protector and often comes to owners’ attention only when Cherry Eye develops. While Cherry Eye can affect any dog, it disproportionately targets certain breeds with distinct facial and eye shapes. Early veterinary care and surgical correction help maintain your pet’s eye health and prevent further issues.

If you're searching for a puppy, always opt for reputable breeders who focus on breeding strategies that reduce inherited eye conditions like Cherry Eye.
