Common Eye Infections in Dogs: Causes, Symptoms, and Treatment

Our furry companions, dogs, have a way of capturing our hearts with their endearing eyes. However, just like humans, dogs can suffer from a range of eye infections that can not only be uncomfortable but also potentially harmful if left untreated. In this article, we will explore some of the most common eye infections in dogs, their causes, symptoms, and appropriate treatments to ensure your canine friend enjoys a lifetime of healthy vision.

  1. Conjunctivitis

Conjunctivitis, also known as “pink eye,” is one of the most prevalent eye infections in dogs. It occurs when the conjunctiva, the thin membrane covering the inner surface of the eyelids and the white part of the eye, becomes inflamed. This inflammation can be caused by allergies, irritants, or bacterial and viral infections. Symptoms of conjunctivitis in dogs include redness, discharge, excessive tearing, and squinting. Treatment may involve cleaning the eyes with a veterinarian-recommended solution and, in some cases, antibiotic or antiviral medication.

  1. Keratitis

Keratitis is the inflammation of the cornea, the transparent front surface of the eye. It can result from injury, foreign objects in the eye, or infections. Dogs with keratitis may exhibit symptoms such as squinting, excessive blinking, cloudy or hazy corneas, and sensitivity to light. Treatment usually involves identifying and addressing the underlying cause and may include medication or, in severe cases, surgery.

  1. Cherry Eye

Cherry eye is a condition in which the gland of the third eyelid, known as the nictitating membrane, prolapses and becomes visible as a red mass in the corner of the eye. While this condition is not typically painful, it can lead to irritation and discomfort for your dog. Surgical correction is often required to reposition the gland and prevent further complications.

  1. Corneal Ulcers

Corneal ulcers are painful sores on the surface of the cornea. They can be caused by trauma, foreign objects, or infections. Dogs with corneal ulcers may display symptoms like squinting, excessive tearing, redness, and discharge. Immediate veterinary attention is crucial to prevent complications, and treatment may include antibiotic eye drops, pain management, and, in severe cases, surgical intervention.

  1. Glaucoma

Glaucoma is a serious eye condition characterized by increased pressure within the eye, leading to damage to the optic nerve and potentially permanent vision loss. Symptoms of glaucoma in dogs include redness, a dilated pupil, cloudy cornea, and a noticeable enlargement of the affected eye. Early diagnosis and prompt treatment with medications to reduce intraocular pressure are essential to manage glaucoma and preserve your dog’s vision.

  1. Entropion and Ectropion

Entropion and ectropion are eyelid conditions that can affect certain dog breeds. Entropion occurs when the eyelid rolls inward, causing the eyelashes to rub against the cornea, leading to irritation and potential corneal damage. Ectropion, on the other hand, is the outward rolling of the eyelid, which exposes the eye’s sensitive tissue to environmental elements. Surgical correction is often necessary to address these conditions and alleviate discomfort.


Your dog’s eyes are not only windows to their soul but also indicators of their overall health and well-being. It is essential to pay attention to any signs of eye discomfort or infection in your furry friend and seek prompt veterinary care when necessary. Regular eye examinations during routine check-ups can help detect and address potential eye issues before they become more severe. By providing the appropriate care and attention to your dog’s eyes, you can help ensure they enjoy a lifetime of clear vision and comfort, allowing them to continue to melt your heart with their soulful gaze.
