Tear Stains in Dogs: Causes, Treatments, and How to Keep Your Pup’s Eyes Bright

If you’ve ever noticed reddish-brown streaks under your dog’s eyes, you’re not alone. These tear stains are a common cosmetic issue in many breeds. While they don’t always indicate a serious health problem, they can be frustrating for pet parents and uncomfortable for dogs if linked to underlying conditions. Understanding why tear stains happen and how to manage them is the first step to keeping your pup’s face clean and healthy.

What are tear stains?

Tear stains are reddish or brownish streaks that appear beneath a dog’s eyes. They’re caused by excessive tearing, which moistens the fur and allows porphyrins (iron-containing molecules found in tears and saliva) to discolor the hair. When the tears sit on light-colored fur, they leave a noticeable stain.

While tear stains are most visible on white or cream-coated dogs, they can affect any breed.

Breeds most prone to tear stains

Certain breeds are more likely to develop tear staining because of their eye and facial structure:

• Toy breeds: Maltese, Shih Tzus, Poodles, Bichon Frises
• Flat-faced breeds (brachycephalic): Bulldogs, Pugs, Pekingese
• Breeds with excessive tearing: Cocker Spaniels, Chihuahuas, Lhasa Apsos

Causes of tear stains in dogs

Tear stains are a symptom, not a disease. They can result from a variety of factors:

1. Excessive Tear Production (Epiphora)

• Overactive tear glands can overwhelm the normal drainage system.
• Can be linked to irritants, allergies, or eyelid/eyelash issues.

2. Blocked Tear Ducts

• The tear ducts normally drain fluid into the nasal cavity.
• If blocked, tears spill over the eyelids and soak the fur.

3. Eye Infections or Irritation

• Conjunctivitis (pink eye), ingrown eyelashes, or foreign objects can irritate the eye and increase tearing.

4. Allergies

• Environmental triggers like pollen, dust, or certain foods may cause watery eyes.

5. Poor diet or water quality

• Diets with fillers, artificial dyes, or high mineral content in water can worsen staining.
• Iron-rich water (from wells) is especially linked to darker stains.

6. Ear Infections or Oral Issues

• Surprisingly, ear infections and dental problems can also cause eye tearing in some dogs.

7. Genetics

• Some dogs are simply predisposed due to anatomy (shallow eye sockets, short muzzles, hair around the eyes).

Health concerns to rule out

While tear stains are often cosmetic, sometimes they point to medical issues that need attention. Call your vet if you notice:

• Sudden increase in tearing
• Red, swollen, or painful eyes
• Pus-like discharge
• Frequent pawing at the eyes
• Squinting or light sensitivity

These could signal infections, ulcers, or more serious eye problems.

How to treat and manage tear stains

1. Daily Cleaning

• Wipe the area under the eyes with a damp cotton pad or pet-safe wipe.
• Use specially formulated tear stain wipes for stubborn buildup.
• Always be gentle to avoid irritating the delicate skin.

2. Keep hair trimmed

• Long hair around the eyes can trap moisture.
• Ask your groomer to keep the fur short and neat.

3. Improve diet and water

• Feed a high-quality, grain-free diet.
• Provide filtered or distilled water to avoid mineral-heavy stains.

4. Eye-Safe Solutions

• Avoid over-the-counter products with harsh chemicals or antibiotics without veterinary guidance.

5. Vet Treatment

• For blocked tear ducts, a vet can flush the ducts under anesthesia.
• If allergies are the culprit, antihistamines or allergy management may be prescribed.
• Infections may require antibiotics or antifungal medications.

Home remedies for tear stains (With vet approval)

Wipe with chamomile tea (cooled): Natural soothing effect for mild irritation.

• Coconut oil: A thin layer under the eyes may help repel moisture.
• Apple cider vinegar in water (tiny amount): Some owners claim it helps balance pH — but always ask your vet first.

Preventing tear stains

• Daily wiping to prevent buildup
• Regular grooming and trimming around the eyes
• High-quality diet and fresh, filtered water
• Routine vet checkups to rule out underlying issues
• Keeping ears clean and healthy (since ear infections can affect tearing)

Tear stains in dogs may seem like just a cosmetic issue, but they can signal underlying health concerns or discomfort. By combining good hygiene, proper diet, and regular vet care, you can reduce staining and keep your dog’s eyes bright and comfortable.

Every pup is unique, so what works for one may not work for another. With patience and the right care, your dog’s eyes can be as happy and sparkling as their wagging tail.
