4 Reasons Why Your Dog Gets Stains on Its Face

Those reddish-brown streaks under your dog's eyes weren't there before. Now, they seem to get darker after every bath.

You clean their face, but the stains keep coming back. What could be causing them?

Dog tear stains and facial discoloration aren't always signs of poor grooming. Sometimes, they're connected to how tears drain or how saliva collects on fur.

Other times, persistent staining may point to an underlying health concern.

Understanding the difference matters. The wrong cleaning approach might irritate your dog's skin without addressing the actual cause.

At Animal Pharmaceuticals, we understand that pet owners want clean coats and comfortable grooming routines.

This guide explains four common reasons dogs develop facial stains and how to manage them safely.

You'll also discover when gentle facial cleaning helps and when your dog needs veterinary attention.

What Causes Brown or Red Stains on a Dog's Face?

Dog face stains often develop when tears or saliva leave pigments on the fur. These reddish-brown pigments, called porphyrins, can become more noticeable on light-colored coats. Excessive tearing, facial anatomy, saliva buildup, and underlying eye conditions may all contribute to facial discoloration.

The location of the stain often provides useful clues.

Brown marks beneath the eyes usually suggest tear staining, while discoloration around the mouth may involve saliva.

However, appearance alone cannot confirm the underlying cause.

Let's explore the four most common explanations.

1. Excessive Tearing Can Cause Reddish-Brown Stains Under the Eyes

Why Do Dog Tears Leave Brown Stains?

Your dog's tears help protect and lubricate their eyes.

However, tears also contain naturally occurring pigments called porphyrins.

When tears repeatedly wet the surrounding fur, these pigments can create reddish-brown discoloration.

Excessive tear overflow is known as epiphora.

Dogs experiencing epiphora may develop persistent staining beneath one or both eyes.

The staining itself may be cosmetic, but excessive tearing can have several causes.

Why Are Tear Stains More Visible on White Dogs?

Light-colored coats make pigment buildup easier to notice.

That's why dog tear stains often stand out on breeds such as:

• Maltese

• Bichon Frise

• White Poodles

• Shih Tzus

• Other light-coated dogs

Dark-coated dogs can experience similar tearing, even when the discoloration isn't obvious.

A white dog's stained fur doesn't automatically indicate poor health.

However, constant moisture can irritate the surrounding skin.

What Should You Do About Excessive Tearing?

Start by observing your dog's eyes.

Are both eyes watering normally, or does one appear noticeably wetter?

Look for redness, squinting, rubbing, or unusual discharge.

If your dog seems comfortable and your veterinarian finds no underlying problem, gentle facial cleaning may help manage buildup.

Important: Cleaning the fur doesn't necessarily stop excessive tear production.

The goal is to manage cosmetic staining while addressing any underlying causes.

2. Your Dog's Facial Shape May Affect Tear Drainage

How Does Facial Anatomy Cause Tear Stains?

Some dogs develop tear stains because their facial anatomy affects normal tear drainage. Shallow eye sockets, prominent eyes, facial folds, or eyelid positioning may cause tears to overflow onto nearby fur. These features can make facial staining more persistent, even when owners maintain regular grooming routines.

Normally, tears drain through small openings near the eyelids.

They travel through the tear drainage system toward the nose.

When drainage is less effective, tears may spill onto the face instead.

Flat-faced breeds can be particularly prone to this problem.

Which Dog Breeds Commonly Experience Tear Overflow?

Pugs, Shih Tzus, and other short-nosed breeds may have facial structures that influence tear drainage.

Some small breeds also experience persistent staining because of their eye and eyelid characteristics.

Long facial hair can complicate matters.

Hair rubbing against the eyes may cause irritation and increased tear production.

However, a dog's breed doesn't confirm the cause of staining.

A veterinarian can assess whether eye anatomy or another condition contributes to the problem.

Can Grooming Help Dogs With Persistent Tear Stains?

Regular grooming can help keep the surrounding fur clean and dry.

It may also prevent hair from collecting moisture around the eyes.

However, grooming cannot correct structural tear drainage problems.

Consider professional grooming when long facial hair requires trimming near the eyes.

Avoid attempting delicate trimming with household scissors.

For dogs prone to recurring stains, consistent facial hygiene is more useful than aggressive stain removal.

3. Saliva, Food Residue, and Facial Moisture Can Stain Fur

Why Does My Dog Have Brown Stains Around Its Mouth?

Brown or reddish stains around a dog's mouth may develop when saliva repeatedly wets the fur. Saliva contains porphyrin pigments that can discolor hair over time. Food residue, drinking habits, and moisture trapped in facial hair or folds may also contribute to an untidy appearance.

Not every brown facial stain comes from tears.

If discoloration appears around your dog's beard or muzzle, saliva may play a role.

Dogs naturally produce saliva while eating, drinking, and grooming themselves.

When saliva repeatedly soaks the same area, staining may become more noticeable.

Do Food and Drinking Habits Affect Facial Staining?

Food particles can stick to longer facial hair.

Drinking may also leave the muzzle damp.

These everyday activities don't necessarily indicate a health problem.

However, prolonged moisture makes routine cleaning more important.

For example, a dog with a long beard may collect food residue around its mouth.

Wiping and drying the area after meals can help maintain cleanliness.

Don't assume changing food or water automatically eliminates facial stains.

Diet-related changes should have a clear reason, especially when your pet has a known medical condition.

Can Facial Folds Make Staining Worse?

Dogs with facial folds may trap moisture, saliva, and debris between skin surfaces.

These areas require particular attention during grooming.

Persistent dampness can contribute to skin irritation.

If the folds develop redness, odor, discharge, or discomfort, contact your veterinarian.

Avoid applying harsh cleansers to sensitive facial areas.

For routine hygiene, choose appropriately labeled products and follow their instructions.

4. Eye Irritation or Underlying Health Problems May Increase Staining

Can Dog Tear Stains Indicate a Health Problem?

Yes. Persistent or suddenly increased tear staining may accompany eye irritation, blocked tear ducts, eyelid abnormalities, allergies, or infection. The stains themselves don't identify a disease. However, redness, pain, unusual discharge, or one-sided tearing requires veterinary evaluation to determine the cause.

Most importantly, don't treat every facial stain as a cosmetic issue.

Some dogs produce additional tears because something irritates their eyes.

Other dogs experience difficulty draining tears normally.

Which Health Problems Can Cause Excessive Tearing?

Possible causes include:

Eye irritation: Dust, foreign material, or misplaced hairs may irritate the eye.

Blocked tear ducts: Reduced drainage can cause tears to overflow.

Eyelid abnormalities: Conditions such as entropion may cause the eyelid to turn inward.

Eye infections: Certain infections can cause tearing, redness, or abnormal discharge.

Allergic conditions: Some allergies may contribute to eye irritation and watering.

Corneal injuries: Scratches or ulcers can cause pain and excessive tearing.

These conditions require different approaches.

A facial wipe cannot treat an infection, correct an eyelid abnormality, or unblock a tear duct.

When Should You Take Your Dog to the Veterinarian?

Arrange prompt veterinary care when you notice:

• Sudden or excessive tearing.

• Staining mainly affecting one eye.

• Redness, swelling, or squinting.

• Yellow or green eye discharge.

• Cloudiness or visible eye discomfort.

• Frequent rubbing or pawing near the eyes.

Eye pain, cloudiness, or suspected injury needs urgent assessment.

Veterinary resources such as VCA Animal Hospitals' guidance on epiphora explain the importance of identifying underlying tear drainage problems.

Treat the cause first. Cosmetic cleaning comes afterward.

How Can You Tell What Type of Facial Stain Your Dog Has?

The location and appearance of discoloration can help guide your next steps.

Remember: Stain color and location provide clues, not a diagnosis.

How to Clean Dog Tear Stains Safely at Home

To clean dog tear stains, gently wipe the surrounding fur with a soft, damp cloth or a product labeled for facial use. Avoid direct eye contact, remove visible debris, and carefully dry the area. Regular cleaning helps manage buildup but may not eliminate established discoloration.

Step 1: Check Your Dog's Eyes First

Before cleaning, inspect the area for redness, discharge, swelling, or discomfort.

If your dog shows concerning symptoms, seek veterinary advice.

Don't scrub an irritated area simply to remove discoloration.

Step 2: Choose a Gentle Facial-Cleaning Product

Use a clean, soft cloth dampened with water or an appropriately labeled pet facial wipe.

Avoid household cleaning products.

Never apply bleach, lemon juice, vinegar, or hydrogen peroxide around your dog's eyes.

These substances can cause irritation or injury.

Step 3: Gently Remove Surface Buildup

Clean the stained fur without pressing against the eyeball.

Use a separate clean section of cloth or wipe for each eye.

Follow the product label's instructions for application.

Stop immediately if your dog shows discomfort.

Step 4: Keep the Fur Dry

After cleaning, gently dry the surrounding fur.

Persistent moisture can contribute to skin discomfort.

Dogs with longer facial hair may benefit from professional grooming.

Avoid pulling at dried debris or aggressively rubbing discolored hair.

Step 5: Maintain a Consistent Routine

Facial staining often develops gradually.

Regular gentle cleaning can help prevent excessive debris and moisture buildup.

However, established pigment may remain visible until the stained hair grows out or is professionally trimmed.

Don't expect an instant transformation after one cleaning session.

For easier daily maintenance, explore grooming products specifically designed for facial and tear-stain cleaning.
