Symptoms of Canine Conjunctivitis

The main symptoms of canine conjunctivitis include: conjunctival hyperemia, flushing, increased secretions from the eyes, red and swollen eyeballs, lacrimation, photophobia, and pain. In severe cases, there may be a yellowish-white pus discharge, even blindness, and the dog may start to scratch its eyes frequently. In this case, we first need to put a protective cover on the dog to avoid further scratching of the eyes, and then take the dog to a pet hospital for inspection promptly.

Canine conjunctivitis can be divided into acute conjunctivitis, chronic conjunctivitis, and purulent conjunctivitis.

1. Acute Conjunctivitis

If a dog has acute conjunctivitis, the main manifestation is congestion of the conjunctiva and the palpebral conjunctiva. If the inflammation involves the bulbar conjunctiva, the inflammatory response is strong. There may be a small amount of serous, purulent, and even pseudomembranous secretions in the eye, conjunctival swelling, pain, narrowing or closure of the palpebral fissure.

1. Chronic Conjunctivitis

If a dog has chronic conjunctivitis, papillae and follicles will form on the surface of the conjunctiva. Although the eye swelling is not obvious, the conjunctiva lacks luster, and sometimes eyelid spasm may occur.

1. Purulent Conjunctivitis

If a dog has purulent conjunctivitis, the skin of the eyelids usually develops dermatitis and itching. If the course of the disease is long, it can also cause corneal opacity. If the dog's eyes itch, try not to let the dog scratch them to avoid infection.
