Why Is My Dog's Eyes Red Around the Outside?

There are many reasons why your dog's eyes may be red. Dogs' eye color is usually brown or hazel, but it can also be blue, green, or orange.

The most common cause of red eye is conjunctivitis, which is inflammation of the membranes that line the eyelids and cover the white part of your dog's eye.

If you see your dog's eyes are red around the outside, this could be due to a number of other causes like allergies, inflammation in the cornea or retina, or dry eye syndrome.

This article will talk about some common causes for dogs with red eyes around the outside.

What is conjunctivitis?

Conjunctivitis, or "pink eye," is a viral infection that affects the outer layer of the eye, including the iris and cornea. The cornea is the clear, cloudy part of the eye responsible for focusing light.

When the cornea becomes irritated, the cornea tends to become red and inflamed. This can lead to redness around the outside of the eye (because it's attached to the eye lid, outside of the cornea).

A condition called "extranodal infection" occurs when bacteria get into the tear film, causing redness at the tear duct. Risk factors: A dog's immune system and genetics may predispose him to conjunctivitis. Many dogs also react to new and common dog food ingredients, like pyridium or sodium oxybate.

What to do for your dog's red eyes

Examination of your dog's eyes is the first step in diagnosing what is causing red eyes.

Your veterinarian should do this first and rule out other possible causes of red eyes like food allergies or an eye infection.

If the exam finds no other cause, then your vet will likely prescribe some medication and eye drops to reduce inflammation and soothe the eyes.

Keep your dog on the eye drops for a minimum of 7 days and then watch to see if your dog's eyes return to normal.

After a couple of days, your dog may start blinking normally and have normal eyes again.

Watch for signs of infection or allergy. You can also check your pet's eyes at home if your veterinarian recommends it.

How to prevent your dog's red eyes

You can buy eye drops and ointments that will help stop eye irritation and redness.

Get your dog vaccinated for fleas and ticks As the weather gets warmer, it is also common to see flea populations in your area grow.

If your dog has been indoor-only since he was a puppy, he may be at risk of developing flea allergies.

Any type of contact with fleas can cause an allergic reaction. Your veterinarian may recommend your dog take a weekly flea treatment to help control flea infestations.

Always make sure your dog is up-to-date on flea and tick medication before bringing him into the home.

Avoid overdoing it on the grooming Overly groomed dogs can rub their eyes and cheeks, which can cause a stye in the conjunctiva.


Sometimes, your dog may just be looking a little less energized than usual, but it's important to get to the bottom of what is causing this.

If your dog is generally healthy, you should not need to seek medical attention for your dog's red eyes.

But, if your dog is otherwise healthy, or has red eyes only around the outside, it is possible that there is something seriously wrong that needs immediate treatment.

If you are concerned that your dog is sick or injured, you should contact a veterinarian right away.
