Entropion in Dogs: Understanding the Inward-Turning Eyelids and its Impact on Canine Health

Entropion is a common eye condition that affects dogs, characterized by the inward rolling or turning of the eyelids. This condition can cause the eyelashes and fur to irritate the cornea, leading to discomfort and potential damage to the eye. In this in-depth article, we delve into the world of entropion in relation to dogs, understanding its characteristics, potential causes, symptoms, methods of diagnosis, available treatments, and strategies for managing this eye condition that can impact the health and happiness of our cherished canine companions.

Understanding Entropion in Dogs

Entropion is a condition in which the eyelids roll inward toward the eye, causing the eyelashes and fur to rub against the cornea and conjunctiva. This rubbing can lead to corneal irritation, pain, and potential corneal ulcers.

Causes of Entropion

Entropion in dogs can be caused by various factors, including:

  1. Breed Predisposition: Some dog breeds are more prone to developing entropion due to their facial anatomy and loose skin around the eyes.
  2. Congenital: Some dogs may be born with entropion, and it becomes apparent at a young age.
  3. Facial Injuries or Scarring: Trauma or scarring around the eye area can lead to the development of entropion.
  4. Old Age: Entropion can occur in older dogs as the tissues around the eye lose elasticity.

Symptoms of Entropion

The symptoms of entropion in dogs may include:

  1. Excessive Tearing: Dogs with entropion may have increased tear production due to eye irritation.
  2. Squinting: Affected dogs may squint or keep their eyes partially closed to reduce discomfort.
  3. Redness and Swelling: The eyes may appear red and swollen due to chronic irritation.
  4. Rubbing or Pawing at the Eyes: Dogs may try to alleviate discomfort by rubbing or pawing at their eyes.

Diagnosing Entropion

Diagnosing entropion involves a thorough eye examination by a veterinarian. Diagnostic tests may include:

  1. Physical Examination: The veterinarian will assess the eye’s structure, eyelids, and cornea for signs of entropion.
  2. Fluorescein Stain Test: This test can detect corneal ulcers or erosions caused by the inward-turning eyelids.

Treatment and Management

The treatment for entropion in dogs depends on the severity of the condition. Treatment options may include:

  1. Medical Management: For mild cases, lubricating eye drops or ointments may be prescribed to reduce eye irritation.
  2. Surgical Correction: Severe cases of entropion may require surgical correction to reposition the eyelids properly.
  3. Post-Surgery Care: After surgery, dogs may require post-operative care and follow-up appointments to monitor healing.


Entropion is a prevalent eye condition in dogs that requires prompt attention to prevent corneal damage and discomfort. Early recognition of symptoms, prompt veterinary attention, and appropriate treatment are vital in managing entropion and supporting affected dogs’ eye health. Understanding the complexities of entropion empowers dog owners and veterinarians to provide the best care and support, ensuring that our furry friends maintain healthy and comfortable eyesight as cherished members of their human families.
