Tear stains in dogs: what to know about causes, care, and prevention

Tear stains in dogs: excessive tearing may cause reddish or brown stains below the eyes, especially in light-colored dogs.

This content is for informational purposes only and does not replace evaluation by a veterinarian. Excessive tearing, persistent stains, redness, discharge, itching, or eye discomfort should always be evaluated by a professional.

Tear stains in dogs are a common term used to describe the reddish or brown marks that appear below the eyes, especially in white or light-colored dogs. Despite the popular expression, the issue is not always related to the acidity of tears themselves. In many cases, anatomical, genetic, environmental, and dietary factors may be involved.

In our family environment, we also follow the routine of an elderly dog named Willy, who gradually developed tear stains as he aged. Continuous observation, proper eye hygiene, and veterinary care became part of his routine over time.

What causes tear stains in dogs?

Tear stains in dogs may be associated with excessive tearing, moisture accumulation below the eyes, and oxidation of substances present in tears. Over time, the fur may become darker, especially in white or light-coated dogs.

Some of the most common causes include:

genetic predisposition;
facial anatomy;
blocked or narrowed tear ducts;
hair too close to the eyes;
environmental or food allergies;
eye irritation;
inflammation;
age-related changes.

Are tear stains in dogs only aesthetic?

Not necessarily. Although many owners seek solutions because of the appearance of the stains, tear stains in dogs may indicate that something deserves closer attention.

When there is intense tearing, odor, itching, redness, or thick discharge, veterinary guidance is recommended. The issue may involve irritation, ophthalmological conditions, or even tear duct obstruction.

Which dog breeds are more prone to tear stains?

Some breeds are more predisposed due to the shape of their eyes, face, and muzzle.

Maltese;
Shih Tzu;
Lhasa Apso;
Pug;
French Bulldog;
Pomeranian;
Yorkshire Terrier;
Bichon Frisé.

In brachycephalic dogs or short-muzzled breeds, tear drainage may be less efficient, favoring moisture accumulation below the eyes.

Can food influence tear stains in dogs?

In some cases, yes. Diet may influence sensitivity, allergies, or increased secretion production in certain dogs. Some owners notice improvement after changing food, especially when reducing products with artificial dyes, preservatives, or low-quality ingredients.

However, there is no single food capable of solving all cases of tear stains in dogs. Each dog should be evaluated individually, especially when food allergies are suspected.

What is the best dog food for tear stains?

The best dog food will depend on the dog’s profile, age, size, digestive health, allergies, and nutritional needs.

In general, many owners look for foods with:

high-quality protein sources;
fewer artificial dyes;
selected ingredients;
good digestibility;
formulas suitable for sensitive dogs.

Even so, dietary changes should be made gradually and preferably with veterinary guidance.

How to help prevent tear stains in dogs

Prevention involves daily care, observation, and moisture control around the eyes.

clean the eye area gently;
keep hair trimmed around the eyes;
avoid aggressive or heavily scented products;
dry the area carefully after cleaning;
offer good-quality food;
observe signs of allergies;
maintain regular veterinary checkups.

Eye hygiene should never be aggressive. The eye area is sensitive and requires gentle care.

Is there a treatment for tear stains in dogs?

There is no universal treatment for tear stains in dogs. The best approach depends on the underlying cause. Allergies, irritation, inflammation, blocked tear ducts, and ophthalmological conditions may all require different approaches.

For this reason, eye drops, ointments, and medications should never be used without professional guidance. Self-medication may worsen the condition and damage the eyes.

When should you see a veterinarian?

Veterinary evaluation is recommended when the dog presents:

sudden excessive tearing;
yellow or thick discharge;
redness;
intense itching;
strong odor;
partially closed eyes;
pain or sensitivity;
rapid worsening of the stains.

These signs may indicate something beyond aesthetic staining.

Tear stains in senior dogs

In senior dogs, tear stains may appear or intensify due to natural aging changes involving the skin, fur, immunity, and eye region.

For this reason, older dogs require even closer observation. Small changes in tearing, odor, or coat discoloration may indicate the need for evaluation.

How to care for tear stains daily

A simple routine may help considerably:

observe the eyes daily;
clean gently with soft gauze when needed;
avoid leaving the area wet;
do not use human cosmetic products;
maintain proper hygienic grooming;
monitor changes in diet;
pay attention to sudden worsening.

Daily observation helps identify when something falls outside the dog’s normal pattern.

Tear stains in dogs: understanding the cause is the first step

Tear stains in dogs may have genetic, anatomical, dietary, environmental, or ophthalmological origins. For this reason, simply trying to remove the stain without understanding the cause is often insufficient.

With proper hygiene, quality nutrition, continuous observation, and veterinary follow-up, many dogs can maintain greater eye comfort and better control of tear staining.
