As pet owners, we often have an abundance of questions about our furry friends. One of the most common questions we may have is why our dogs have brown eyes. While the answer may seem simple enough, it is actually quite complex. It is important to understand why our dogs’ eyes are brown in order to ensure that their eyes stay healthy and their vision remains clear. In this blog post, we will explore the science behind why our dogs’ eyes are brown, as well as important considerations for eye health in order to keep our canine companions seeing clearly. We will also look at how our dogs’ eye color can be affected by genetics and environmental factors. So, if you’ve ever asked yourself “Why are my dogs’ eyes brown?”, then stay tuned to find out!
Diagnosis of Pigmentary Keratitis in Dogs
A pet owner may occasionally notice the eye discoloration and take their dog to the vet. Other times, there are no overt symptoms, but a thorough examination by the veterinarian reveals the pigment. The corneal surface may become more visible and exhibit signs of trauma when examined with a lighted ophthalmoscope.
The veterinarian will examine your pet’s eyes and check for any conditions that could be causing the inflammation. A fluorescein stain can show ulcers, a Schirmer tear test may show a persistent dry eye, and eyelid or lash malformations may be easily noticeable. An intraocular pressure test can detect glaucoma, and cultures can be sent to the lab to look for fungi or bacteria if an infection is suspected.
Recovery of Pigmentary Keratitis in Dogs
Dogs with pigmentary keratitis require lifelong, persistent medical care. Regular follow-up appointments with the veterinarian will enable them to evaluate the efficacy of treatments and keep an eye on any new lesions or the development of existing ones.
Changes in the environment and behavior may be advised, especially if they could prevent chronic eye inflammation and irritation. The puppy shouldn’t be permitted to hang their head out the window while riding in a car due to the risk of harm from insects, dust, and pebbles. If the dog is willing to wear them, dog goggles are available to protect the eyes.
Infections typically have a good prognosis, but the outcome of corneal ulcers depends on how severe they are. Resolution of the ulcers’ cause is necessary to improve outcomes.
Pigmentary keratitis in dogs can be expensive to treat. If you think your dog might get pigmentary keratitis, look into pet insurance right away. Pet owners can compare insurance policies from well-known companies like PetPlan and Embrace using Wag! Wellness. With just a few clicks, find your pet’s “pawfect” plan!
An 8-month-old English bulldog with a unilateral smoky-colored sclera is one of my patients (see image on the left). I’ve never seen this before, so I’m curious what you think.
It is important to distinguish between this gray-appearing scleral pigmentation and a very thin sclera, which is dark-blue due to the dark uveal tract that can be seen through the thin sclera. The presence of staphyloma, a scleral defect lined with uveal tissue, is the most frequent cause of scleral thinning. In contrast to the pigment in this bulldog, a staphyloma is typically limited to a small area of the eye and does not affect the entire sclera. Staphylomas also frequently protrude from the ocular surface (Figure 2). Congenital scleral formation defects or traumatic injury can cause them. Staphylomas should be surgically removed if they have traumatic origins. Congenital staphylomas that are large may also be surgically removed, but if they are small, they are frequently left untreated.

A. In your photograph, the bulldog has more extensive scleral and episcleral pigmentation than is typical for dogs, but this is normal. The thickness of the stroma, the amount of pigment it contains, and the amount of fat in the outer boundary all affect the sclera’s color in dogs. Some people’s sclera appears whiter at the limbus because it is thicker there and thins toward the equator of the earth. But dogs frequently have a lot of limbal melanin, which gives the limbus a dark-brown or black appearance. Sometimes, this pigment may surround the entire limbus posteriorly for a few millimeters or it may be especially noticeable laterally (Figure 1). Your bulldog’s sclera appears gray because of the melanin that is lightly dispersed throughout it. Additionally, the pigment covers the entire sclera rather than being concentrated in one area. This may be related to the dogs coat color. Advertisement.
FAQ
Is it normal for dogs eyes to be brown?
The border between the cornea and the sclera (the white of the eye), also known as the corneal limbus, is where the sclera is thicker. It contains stem cells in its palisades of Vogt. Among other problems, it may be impacted by cancer or aniridia (a developmental issue). https://en. wikipedia. Corneal limbus is described in Wikipedia as thinnest at the equator of the earth and appearing whiter at the limbus in some people. But dogs frequently have a lot of limbal melanin, which gives the limbus a dark-brown or black appearance.
Why are my dogs eyes not white?
What does a dog’s cloudy eye mean? Cloudy eyes may be a sign of glaucoma, nuclear sclerosis, dry eye, or corneal dystrophy, among other eye diseases. It’s best to seek medical attention as soon as you can if you notice that your dog’s eye is becoming opaque to determine the cause.
Why did my dog’s eyes go from blue to brown?
Another condition that affects the dog’s eyes and alters the color of their eyes, nuclear sclerosis, is normal. The alteration in the color of the dog’s lenses is known as nuclear sclerosis, also referred to as lenticular sclerosis. As dogs age, this is a typical process that takes place.
Does pigmentary keratitis cause blindness?
The term “pigmentary keratitis” refers to the progression of corneal pigmentation brought on by persistent inflammation [1]. If PK crosses the visual axis, it can significantly impair vision and, in extreme cases, result in blindness [2, 3].
