Entropion - inward-rolled eyelid in dogs

Important beforehand: Fidello is not a veterinarian. This page is intended to inform you and does not help you reach a diagnosis. Are you unsure about your dog's health, or do you recognize the signs described below? Always contact a veterinarian.

Entropion is an eyelid condition in which the edge of the eyelid curls inward, so that eyelashes and fur rub against the cornea and conjunctiva. This is not only uncomfortable for the dog, it can also cause real eye damage over time. The condition is relatively common, especially in certain breeds, and can usually be corrected well with timely treatment.

What is entropion?

In a healthy eyelid, the edge lies neatly against the eyeball, with the eyelashes pointing outward. With entropion, the eyelid margin - usually the lower eyelid, but the upper eyelid or both eyelids can be affected as well - rolls inward. Fur and eyelashes then come into contact with the cornea, which can cause irritation, excessive tearing, and eventually damage to the cornea. Entropion can be congenital, often related to skull shape or excess skin around the eyes, or acquired, for example through scarring after a previous eye infection or injury, or because a dog keeps squinting due to pain.

Which dogs are at risk?

Entropion is reported more often in breeds with a lot of skin folds around the eyes or a specific skull shape, such as the Chow Chow, the Shar Pei, the English Bulldog, the Mastiff and Bullmastiff, and the Saint Bernard - in these breeds the condition can also be more pronounced. It is also regularly reported in the Cocker Spaniel, Golden Retriever, Labrador Retriever, Pug, Boxer, Cavalier King Charles Spaniel, Irish Setter, Springer Spaniel, Poodle, Great Dane and Chesapeake Bay Retriever. A hereditary predisposition appears to be the most important risk factor; this does not mean that every dog from a susceptible breed will develop the condition.

Symptoms

Early signs are often subtle: excessive tearing, a half-closed eye, mild redness of the white of the eye or conjunctiva, and a dog that rubs its eye with a paw or rubs its head against furniture. With ongoing irritation, mucous or pus-like discharge can develop, and squinting (blepharospasm) becomes more noticeable. Signs that require urgent attention are: a suddenly cloudy or greyish cornea, obvious pain, an eye the dog no longer wants to open, or visible damage to the surface of the eye.

When to see the veterinarian?

Contact a veterinarian for persistent tearing, repeated squinting of an eye, redness that does not go away on its own, or a dog that is noticeably bothered by its eye. Do not wait if the cornea becomes cloudy, there is clear pain, or the eye stays closed - this can indicate corneal damage and requires prompt assessment.

How is it diagnosed?

A veterinarian assesses the position of the eyelid and the way the eyelashes and fur touch the surface of the eye, often with the help of a light source and magnification. A dye (fluorescein) can be used to check whether the cornea is already damaged. This page cannot tell you whether your dog has entropion; only a veterinarian can determine that after examination.

Treatment in outline

The approach depends on age, severity and cause, and is determined by the veterinarian. In young puppies, temporary stitches are sometimes used to pull the eyelid outward, protecting the cornea while the skull is still growing; these stitches are usually removed after a few weeks and can be repeated if necessary. For persistent or severe entropion, surgical correction is common, in which a small piece of skin near the eyelid is removed so that the margin turns outward again. Such procedures are usually only performed once the skull has largely finished growing. There is no treatment that works the same way for every dog; the treatment plan is always tailored to the individual dog.

What you can do yourself

Besides the treatment prescribed by the veterinarian, you can contribute to comfort at home: keep the eye clean as advised by the veterinarian, prevent your dog from rubbing its eye with a paw (a protective collar can help with this), and follow up on check-up appointments after a procedure. Never use eye drops, ointment or other products yourself without consulting the veterinarian. This does not replace medical treatment, but can contribute to your dog's daily comfort.

Prevention and responsible breeding

In breeds with an increased risk, it is important to be cautious about breeding with dogs that have (had) entropion themselves, and to avoid extreme selection for excess skin folds or a skull shape that increases the chance of entropion. A veterinarian can assess the eyelids of breeding dogs before they are used for breeding. As a buyer of a puppy from a susceptible breed, ask whether the parent dogs have been checked for eye abnormalities.

Living with entropion

After successful treatment, the outlook for most dogs is good and the symptoms disappear. In breeds with a lot of excess skin around the eyes, such as the Shar Pei, the eyelid may roll inward again over time, meaning an additional procedure may be needed. Regular eye checks, especially in susceptible breeds, help to detect a recurrence of symptoms early.

Frequently asked questions

Is entropion painful for my dog?
The constant rubbing of eyelashes and fur along the cornea is uncomfortable and can become painful, especially with prolonged irritation. Early treatment prevents it from getting to that point.

Can entropion resolve on its own in a puppy?
A mild form in young puppies can sometimes lessen as the skull grows, but this is not guaranteed. A veterinarian can assess whether waiting is appropriate or whether treatment is needed.

Can entropion occur in one eye, or is it always both?
Entropion can occur in one eye, in both eyes, and in the lower, upper, or both eyelids. The veterinarian assesses this for each eye separately.

Is surgery always necessary?
Not always. In young puppies, a temporary, less invasive solution is often tried first. Whether a permanent operation is needed is determined by the veterinarian after examination.

Conclusion

Entropion is a common eyelid condition that deserves attention in dogs - especially in certain breeds. Taking early signs such as tearing and squinting seriously, and consulting a veterinarian in time, makes the difference between a dog with prolonged eye irritation and a dog that, with the right treatment, can once again live comfortably.
