If your dog has reddish-brown colored stains under their eyes, it’s not typically a major concern. These marks are tear stains and are extremely common — especially among dog breeds with lighter-colored fur, prominent eyes and uniquely positioned tear ducts. In fact, all dogs have some tear staining, but the exact amount varies by pup.

Though tear stains are usually harmless and purely a cosmetic annoyance, they can occasionally point to underlying health or environmental issues that you shouldn’t ignore.

In this article, we’ll explore the causes of tear stains, what they mean for your dog’s well-being, and some helpful tips on how to manage or prevent them.

Tear stains are discolorations that form beneath a dog’s eyes, typically in rust-colored streaks. They’re caused by excess tear production or poor drainage, which allows moisture to accumulate and stain a dog’s fur.

Tear stains are most often seen in breeds like Maltese, Poodles and Shih Tzus. While tear stains are usually harmless, they can sometimes signal a larger health issue like an eye infection, a blocked tear duct or allergies.

Tear stains can be the result of a variety of factors, but they are often due to your dog’s unique anatomy and health. Some breeds are simply more likely to develop these unsightly brown stains under their eyes than others.

For example, brachycephalic dogs with short muzzles are especially prone to tear staining due to poorly angled tear ducts. These ducts can make it harder to effectively drain tears, allowing moisture to pool beneath the eyes.

Eyelid issues like everted (rolled-out) or inverted (rolled-in) eyelids and ingrown eyelashes can also contribute to tear production and staining. Additionally, porphyrin — a natural iron-containing molecule present in tears — plays a role. Some breeds, like bulldogs and pugs, produce higher levels of porphyrin, which intensifies the reddish-brown discoloration.

Diet can also be a culprit. Food allergies or sensitivities can make tear staining worse, as can underlying medical conditions like eye infections, yeast infections, glaucoma, dental problems and even certain medications or supplements, particularly iron. If you think your dog may have allergies, you should check in with your vet to confirm.

It’s also worth noting that tap water can contribute to tear stains in dogs. If you live in an area that treats its water heavily, there may be higher iron and magnesium levels, which can give off an orange color. This can cause some staining on your pup’s face. A solution to this is to give your dog filtered drinking water instead of water from the tap.

Luckily, there are simple, natural ways you can prevent and treat tear stains in dogs that consist of simple adjustments to their grooming, diet and/or environment.

Daily grooming is one of the easiest ways to reduce tear stains. Gently wipe your pup’s eye area with a damp, soft washcloth or cotton ball to remove tear residue before it can stain their fur.

It’s also important to keep the fur around their eyes neatly trimmed to prevent the buildup of moisture and irritation. Regular grooming not only minimizes tear stains but also reduces the risk of infection caused by trapped debris.

Local pet supply stores usually carry a selection of herbal and all-natural tear stain removers, as well — just be careful to avoid getting any in your dog's eyes. If you don't trust your shaky hands to the task, ask your groomer if they can help at your next appointment.

Your dog’s diet can have a significant impact on tear stains. A high-quality, minimally processed diet can reduce eye irritation due to allergies or sensitivities and promote healthy tear production.

Common food allergies in dogs include chicken, beef, dairy products, eggs, soy, lamb and wheat. If you suspect your pup has a food allergy or sensitivity, consult your veterinarian. They can run an allergy panel or help you use an elimination diet to uncover the culprit.

Also, consider switching to a trusted brand that uses all-natural, human grade whole food ingredients. We love The Honest Kitchen’s Dehydrated Grain Free Chicken recipe, which uses nutritious ingredients like free range chicken, flaxseed, sweet potatoes, apples, celery, pumpkin, cabbage, banana, green beans and more.

Steer clear of food with artificial additives and dyes, which can further contribute to staining. Even natural dyes can stain your pup’s fur if it’s light in color. And always be sure you have fresh water available for your pup, as hydration helps flush out impurities.

Environmental factors like dust, smoke and excessive moisture can worsen tear stains in dogs. High humidity, in particular, can exacerbate staining by keeping fur around the eyes moist, which promotes bacterial growth. If you live in a humid climate, consider using a dehumidifier in your home, and be sure to sanitize water bowls and food bowls regularly to avoid bacteria buildup.

Just like humans, dogs can have an allergy to dust mites that causes itching, skin and coat issues, and runny eyes (epiphora). Try to minimize irritants by keeping your dog’s sleeping area clean, dry and free of potential allergens. Regularly wash their bedding and keep up with vacuuming, both of which can help reduce exposure to particles that may irritate your dog’s eyes.

While tear stains are often manageable at home with natural methods, there are times when professional care may be necessary. If tear stains develop suddenly, especially in a short-snouted breed at risk for eye problems, or are accompanied by redness, swelling or excessive tearing, take a trip to the vet. They can rule out underlying medical issues.

For persistent issues, consider seeing a veterinary ophthalmologist who can assess for more complex conditions. They can provide more comprehensive care with specialized equipment and may even help detect eye conditions early before they can cause damage to your pup’s vision.

Managing your dog’s tear stains may feel like a never-ending battle, but they’re typically harmless, often linked to anatomy, diet and environment. With consistent grooming, thoughtful environmental adjustments and a high-quality diet, you can reduce tear stains and support your dog’s skin, coat and overall health.

Since nutrition plays a vital role, The Honest Kitchen’s human grade dog food and treats can be a great solution.
