Which Breeds are Affected by Entropion?
Eyelid entropion in dogs occurs when an abnormality causes one or both of a dog’s eyelids to become inverted, or rolled inward. It is a genetic condition that can lead to an eyelash or hair irritating the surface of the cornea, and can result in corneal ulceration or perforation. Entropion “can also cause dark-colored scar tissue to build up over the wound,” says PetMD. In some cases, entropion can lead to an inference in your dog’s vision.
Entropion is a hereditary disorder that is commonly seen in a variety of breeds. Those most often affected by it are short-nosed breeds, giant breeds and sporting breeds. According to VCA Hospitals, the following breeds are most likely to develop this condition:
- Golden Retriever
- Great Dane
- Labrador Retriever
- Shih Tzu
- Siberian Husky
- Yorkshire Terrier
What are the Symptoms of Entropion in Dogs?
Symptoms of entropion vary depending on dog size. For smaller dogs, like toy breeds, a leading symptom of entropion is excess tears and inner eye inflammation. PetMD also states that, “in giant breeds, it is more common to see mucus or pus from the outer corner of the eye.” Other breeds may exhibit eye tics, pus or eye inflammation.
What are the Causes of Entropion in Dogs?
Entropion is a genetic condition primarily caused by facial structure. According to PetMD, in short-nosed breeds, the tension of the ligaments around the inner eye is higher than normal, and facial structure, particularly around the nose, can lead to the top and bottom eyelids rolling inward towards the eyeball. The site adds that, “giant breeds have the opposite problem. They have excess slack in the ligaments around the outer corners of their eyes.” In giant breeds, entropion will cause the eyelids to fold inwards.
While entropion is primarily caused by a genetic disposition, repeated incidents of conjunctivitis or inflammation of the chewing muscles can lead to functional entropion. Additionally, severe weight loss in dogs can lead to a loss of fat around the eye socket and cause entropion.
How Is Entropion in Dogs Diagnosed?
If you notice your dog exhibiting the signs of entropion, immediately seek medical attention for your dog from his veterinarian. Your vet will perform a thorough examination before diagnosing your dog. Diagnosis for entropion is fairly straightforward. If your dog is diagnosed, your vet will be able to determine the underlying causes, usually genetic disposition, before recommending treatment.
