dog eye infections

Does your dog keep scratching his eyes these days? Do you notice that his eyes are constantly red, and sometimes discharge comes out from their eyes? If your answer is yes, then there are chances that your furry friend is suffering from an eye infection. Yes, just like humans, they can too are prone to eye problems, and these days it is quite commonly seen in many dogs. To help you understand the eye infection in dogs, we are going to share all the information about it, such as the major signs of a dog eye infection, causes, treatment, and how you can prevent them.

What are the reasons behind all these infections? Actually, there is no specific one. But it is really challenging to determine whether it is just an allergy or some severe underlying eye issue. A dog with an eye infection has itchy, swollen, and red eyes, and sometimes a white or yellow discharge is released by the eyes.

5 Types of Eye Infections in Dog

5 Types of Eye Infections in Dog

Below is the list of five eye problems that are commonly seen in dogs:

1. Conjunctivitis

Commonly known as pink eye or red eye, Conjunctivitis is an inflammation of the conjunctiva, a thin mucous membrane (It is a membrane covering the inside of the eyelid of dogs and the front of the eye). Viruses or bacteria mainly cause it, and sometimes there may be clear or mucous discharge from the eye.

2. Inflammation of the Cornea

Another eye infection that is commonly seen in canines is the Keratitis. It refers to the cornea’s inflammation, and it is of two types: Noninfectious Keratitis and Infectious Keratitis. Minor injuries generally cause noninfectious Keratitis, but the infectious Keratitis can be caused by many factors such as infections, bacteria, parasites, or even a fungal infection.

This infection develops when your dog has inadvertently scratched the cornea. An increase in the disease can cause canine corneal ulcers that can break the eye globe.

3. Uveitis

Uveitis is an inflammation in the interior portion of your dog’s eye. This part consists of the iris, the ciliary body (a round structure located behind the iris), and the choroid (tissues behind the iris).

If your dog’s eye has redness, a cloudy appearance, blood on the inside of the eyes, there may be chances that he is suffering from this eye disease. The common cause of this infection may include other infectious diseases such as blastomycosis or leptospirosis, or other viral, bacterial, fungal, protozoal, and rickettsial causes. If not treated immediately, the condition can lead to blindness.

4. Keratoconjunctivitis Sicca (Dry Eye)

This is a condition in which there is insufficient production of tears in your dog’s eyes. This usually happens when your dog is not able to produce enough tears to smooth their eyes, and that is why the eyes become very dry, and this results in corneal damage. This also develops the risk of ulcers (sores) on the eye, requiring long-term treatment.

5. Abnormalities in the Eyelids and Tear Glands

There are many reasons why your dog may suffer abnormalities in his eyes. Some of them may be due to genetic factors, race, or underlying dog health conditions/diseases and related issues.
