Tear stains are one of the most common grooming concerns dog owners face, especially with light-colored breeds. Those reddish-brown streaks beneath the eyes can make even a healthy dog appear unclean or uncomfortable. While tear stains are often harmless, they can sometimes signal an underlying issue that needs attention.
The good news is that many tear stains can be reduced or managed with proper grooming, diet adjustments, and regular care. Understanding why tear stains happen is the first step toward keeping your dog’s face cleaner and healthier.
This guide explains the causes of tear stains, safe cleaning methods, prevention tips, and when it’s time to visit the veterinarian.
What Are Tear Stains on Dogs?
Tear stains are dark streaks that appear beneath a dog’s eyes. They are usually reddish, rust-colored, or brown and are most visible on white or light-colored dogs.
The staining happens when tears remain on the fur for long periods. Dog tears contain compounds called porphyrins, which contain iron. When exposed to air, these compounds create the reddish-brown discoloration commonly seen around the eyes.
Some dogs naturally produce more tears than others, while some develop tear stains because of irritation, allergies, or blocked tear ducts.
A small amount of tearing can be normal, but excessive tearing may indicate a medical or grooming issue.
Common Causes of Tear Stains
Genetics and Breed Traits
Many dogs are genetically more likely to develop tear stains. Flat-faced breeds often have shallow eye sockets and facial folds that make proper tear drainage difficult.
Dogs with long facial hair may also trap moisture around the eyes, creating an ideal environment for staining and bacterial growth.
Excessive Tearing (Epiphora)
Excessive tearing, also called epiphora, is one of the main causes of tear stains.
This can happen because of:
- Blocked tear ducts
- Eye irritation
- Dust or debris
- Eyelashes rubbing the eye
- Allergies
- Eye infections
When tears cannot drain properly, they overflow onto the fur.
Diet and Water Quality
Low-quality food may contribute to inflammation and allergies that increase tear production. Artificial dyes, preservatives, and fillers sometimes worsen staining in sensitive dogs.
Some pet owners also notice improvements after switching from tap water to filtered water, especially in areas with high mineral content.
Eye Infections or Health Problems
Persistent tearing may signal an infection or medical issue.
Possible causes include:
- Bacterial infections
- Yeast buildup
- Ingrown eyelashes
- Glaucoma
- Dental issues affecting tear ducts
If tear stains suddenly become worse or are accompanied by redness or odor, veterinary care is important.
Dog Breeds Most Prone to Tear Stains
Some breeds naturally develop tear stains more often than others.
Common examples include:
- Maltese
- Shih Tzu
- Poodle
- Bichon Frise
- Pekingese
- French Bulldog
- Chihuahua
White and cream-colored dogs tend to show stains more clearly, but dogs of any color can experience excessive tearing.
How to Safely Clean Tear Stains
Daily Face Cleaning Routine
Consistency is the key to reducing tear stains.
Use a soft cloth or cotton pad dampened with warm water to gently wipe beneath your dog’s eyes once or twice daily. Always wipe outward and avoid touching the eyeball directly.
Dry the area afterward to prevent moisture buildup.
Daily cleaning helps prevent tears from soaking into the fur and creating darker stains over time.
Pet-Safe Tear Stain Wipes
Many pet stores sell tear stain wipes specifically designed for dogs.
Look for products with gentle ingredients such as:
- Aloe vera
- Chamomile
- Saline solution
Avoid products containing harsh bleach-like chemicals or strong fragrances.
Never use human makeup wipes or skincare products near your dog’s eyes.
Homemade Cleaning Solutions
Some dog owners prefer simple homemade options.
A mild saline solution can help clean dried tear residue safely. Another popular option is applying a tiny amount of coconut oil beneath the eyes. Coconut oil may create a protective barrier that keeps tears from soaking into the fur.
Always use caution around the eyes and discontinue any product that causes irritation.
Grooming Tips to Prevent Tear Stains
Trim Hair Around the Eyes
Long hair around the eyes traps moisture and debris.
Keeping facial fur trimmed helps reduce irritation and allows tears to dry more easily. Use blunt-tip grooming scissors or ask a professional groomer for help.
Keep the Face Dry
Moisture encourages bacteria and yeast growth, which can worsen staining.
After drinking water, eating, or going outside in wet weather, gently pat your dog’s face dry.
Some owners use grooming powder around the eyes to absorb excess moisture, but only pet-safe products should be used.
Regular Bathing and Grooming
Regular grooming prevents dirt and oils from building up around the eyes.
Bathing your dog every few weeks with a gentle dog shampoo can help maintain cleaner facial fur and reduce odor.
Professional grooming may also help manage severe staining in long-haired breeds.
Best Diet Changes for Reducing Tear Stains
Improve Food Quality
Diet can influence skin and eye health.
Switching to a higher-quality dog food with natural ingredients may help reduce inflammation and allergies.
Look for foods with:
- Real meat as the main ingredient
- Limited fillers
- No artificial colors
- No unnecessary preservatives
Some dogs experience fewer tear stains after changing protein sources or switching to grain-free formulas, although every dog is different.
Switch Water Sources
Hard tap water may contain minerals that contribute to staining in some dogs.
Using filtered or purified water may help reduce buildup around the eyes over time.
Food Sensitivities and Allergies
Food allergies can trigger excessive tearing.
Common triggers include:
- Chicken
- Beef
- Dairy
- Wheat
- Corn
- Soy
If you suspect food allergies, consult your veterinarian about an elimination diet.
Natural Remedies for Tear Stains
Apple Cider Vinegar
Some dog owners add small amounts of apple cider vinegar to food or water because they believe it changes tear chemistry.
However, results vary, and excessive use may upset your dog’s stomach.
Always consult a veterinarian before adding supplements or vinegar to your dog’s diet.
Probiotics for Dogs
Healthy digestion supports the immune system and may reduce inflammation.
Dog-specific probiotics may help some pets with allergy-related tear staining.
Choose veterinarian-approved probiotic products designed for dogs.
Blueberries and Antioxidant-Rich Foods
Foods rich in antioxidants may support overall eye and skin health.
Small amounts of dog-safe fruits such as blueberries can be a healthy addition to your dog’s diet when fed in moderation.
Products That May Help With Tear Stains
Tear Stain Removers
There are many commercial products designed to reduce tear stains.
These products come in forms such as:
- Wipes
- Powders
- Liquids
- Gels
Choose products specifically made for dogs and follow directions carefully.
Stainless Steel Food and Water Bowls
Plastic bowls can trap bacteria that irritate sensitive skin.
Switching to stainless steel bowls may help reduce bacterial buildup around the mouth and eyes.
Wash bowls daily for the best results.
Dog Eye Combs and Brushes
Fine-tooth eye combs can help remove dried debris beneath the eyes.
Gentle brushing also prevents matting around the face.
What NOT to Do
Some cleaning methods can seriously harm your dog’s eyes or skin.
Avoid:
- Hydrogen peroxide near the eyes
- Human skincare products
- Bleach-based cleaners
- Harsh scrubbing
- Over-cleaning sensitive skin
- Unapproved antibiotics
Using unsafe products may worsen irritation or damage the eyes.
Always prioritize gentle and pet-safe care.
When to See a Veterinarian
Mild tear staining is usually cosmetic, but some symptoms require professional evaluation.
Contact your veterinarian if your dog has:
- Sudden excessive tearing
- Red or swollen eyes
- Yellow or green discharge
- A foul smell around the eyes
- Squinting or pawing at the face
- Vision changes
- Pain or discomfort
A veterinarian can check for infections, blocked tear ducts, allergies, or other medical conditions.
Can Tear Stains Be Prevented Completely?
In some dogs, tear stains can be greatly reduced but not fully eliminated.
Breeds that naturally tear more often may always have some staining. The goal is usually management rather than complete prevention.
Consistent grooming, proper nutrition, regular face cleaning, and addressing health problems early can make a major difference.
