Understanding Canine Pink Eye: Symptoms and More

Canine pink eye, also known as conjunctivitis, is a common condition in dogs that can cause discomfort and irritation. This eye infection or inflammation of the conjunctiva—the mucous membrane that lines the inner surface of the eyelids and the outer surface of the eyeball—can be caused by various factors, including allergies, infections, and irritants. Recognizing the symptoms of pink eye in your pet is crucial for timely treatment and to prevent further complications.

Symptom 1: Redness

One of the most noticeable symptoms of canine pink eye is redness in the affected eye or eyes. The redness is due to the inflammation of the conjunctiva, which becomes more visible as the blood vessels in the area dilate. If you notice that your dog's eyes appear redder than usual, it could be an early sign of pink eye.

Symptom 2: Discharge

Another common symptom of pink eye in dogs is discharge from the eyes. This discharge can vary in consistency and color, ranging from a watery fluid to a thick, pus-like substance. The color may also change, with a clear discharge being less severe than a yellow or greenish one, which could indicate a bacterial infection.

Symptom 3: Swelling

Swelling around the eyes is a clear sign that something is amiss. In cases of pink eye, the eyelids may become puffy and swollen, making it difficult for your dog to open its eyes. Swelling can also cause discomfort and pain, leading to additional symptoms such as pawing at the eyes or rubbing them against surfaces.

Symptom 4: Itching and Scratching

Dogs with pink eye often experience itching and scratching around their eyes. This is a natural response to the irritation caused by the inflammation and discharge. However, excessive scratching can lead to further irritation and even damage to the cornea, so it's important to address this symptom promptly.

Symptom 5: Sensitivity to Light

Some dogs with pink eye may exhibit sensitivity to light, also known as photophobia. This sensitivity can cause them to squint or avoid bright lights, as the inflammation makes the eyes more sensitive to light exposure. If your dog seems to be uncomfortable in well-lit areas or avoids bright environments, it could be a sign of pink eye.
