Overview
Brown discharge around a dog’s eyes is often dried tear staining or discharge that’s built up and changed colour as it dries. It can happen for a few different reasons, from mild irritation or blocked tear drainage to an eye infection or a problem with the eyelids, lashes or surrounding skin.
If your dog seems otherwise well, it’s often worth checking the eyes closely first. If the discharge is new, heavy, smelly, one-sided, or comes with redness, squinting or rubbing, it’s sensible to get veterinary advice.
Things To Check
1. Check whether the discharge is on one eye or both eyes, and whether it keeps coming back after you wipe it away.
2. Look closely for redness, swelling, squinting, blinking, cloudiness, or your dog trying to rub the eye.
3. Notice the colour and texture. Brown staining can be dry and crusty, but thick, yellow, green or sticky discharge is more concerning.
4. Check for hair, dust, grass seeds or anything else that might be irritating the eye area.
5. Have a look at the skin under the eye for moisture, soreness, scabs or a bad smell.
6. Think about whether it happens after walks, windy weather, grooming, sleeping, or in certain environments.
7. If your dog has long facial hair or folds around the eyes, check whether the area is staying damp or dirty.
Common Causes
The most common reason is tear staining. Tears can dry on the fur and leave a brown mark, especially in dogs with lighter coats or more facial hair around the eyes.
Mild irritation is another common cause. Dust, pollen, wind, shampoos, grooming products or hair touching the eye can all lead to extra tearing and staining.
Blocked or narrowed tear ducts can cause tears to overflow and stain the fur. This can happen even if the eye itself doesn’t look very red.
Eye infections, inflamed eyelids, a turned-in eyelid, a misplaced eyelash or a small scratch on the eye can also lead to discharge. These usually cause other signs too, such as squinting, redness or discomfort.
Less commonly, dental issues, skin problems or changes in the shape of the face and eyelids may play a part, especially if the discharge keeps coming back.
What To Do
Gently wipe away any discharge with clean, damp cotton wool or a soft pad, using a fresh piece for each eye. Keep the area dry and avoid rubbing.
Check whether the discharge returns quickly after cleaning. If it does, or if it looks thicker or darker over time, make a note of when it happens and what else you can see.
Keep facial hair trimmed away from the eyes if it tends to get wet or poke the eye area, and make sure grooming products aren’t getting into the eyes.
Try to reduce obvious irritants where possible, especially dust, grass seeds and strong shampoos around the face. If the eye looks sore, cloudy or your dog is bothered by it, don’t wait to see if it settles on its own.
For brown staining without other signs, regular gentle cleaning and monitoring is often the most useful first step.
When To Contact A Vet
Speak to your vet if the discharge is only in one eye, is thick or smelly, or is happening alongside redness, squinting, swelling, cloudiness or rubbing. These signs can suggest irritation or an eye problem that needs a proper check.
You should also get advice promptly if the discharge started after a scratch, bump, or possible foreign body, or if it keeps coming back despite gentle cleaning.
