How Do I Fix Tear Stains on My Maltese?
A comprehensive guide to understanding, preventing, and treating tear stains in Maltese and white-coated dogs.
What Causes Tear Stains?
Tear stains — the reddish-brown discoloration that appears below a dog's eyes — are caused by porphyrins. These are iron-containing molecules produced during the normal breakdown of red blood cells. When porphyrins are excreted through tears (as well as saliva and urine), they oxidize upon contact with air and turn that characteristic rusty-red color. This is especially visible on white or light-colored coats like those of Maltese dogs.
6 Common Causes of Excessive Tear Staining
Anatomical Factors
Some dogs have naturally shallow tear ducts, blocked nasolacrimal ducts, or eyelid abnormalities that cause tears to overflow onto the face rather than draining normally. This is especially common in dogs bred for flatter faces.
Dietary Issues
Food allergies or sensitivities can increase tear production. High-mineral tap water can also contribute — the excess minerals are excreted through tears. Switching to filtered or bottled water often makes a noticeable difference.
Environmental Allergens
Pollen, dust, smoke, perfumes, and other environmental irritants can cause eye irritation and increased tearing. Dogs living in smoky environments or high-allergen areas are more prone to staining.
Infections and Inflammation
Bacterial or yeast overgrowth in the moist area under the eyes, conjunctivitis (pink eye), or other eye infections can dramatically increase tear production and staining. If staining is sudden or severe, a vet visit is warranted.
Teething in Puppies
Many Maltese puppies experience a dramatic increase in tear staining during the teething phase (approximately 3-6 months). This is temporary and usually resolves once adult teeth come in.
Stress
Significant stress or anxiety can increase tear production. A new home, changes in routine, or separation anxiety may trigger or worsen tear staining.
Prevention Tips
- ✓Feed a high-quality diet with 30% protein or less to reduce kidney and metabolic stress (see our Feeding & Nutrition guide)
- ✓Use filtered or bottled water — high mineral content in tap water is a common culprit
- ✓Wipe under your dog's eyes daily with a soft, damp cloth or grooming wipe to remove tear residue before it oxidizes
- ✓Keep the facial hair trimmed around the eye area to prevent moisture accumulation
- ✓Schedule regular veterinary checkups to rule out blocked ducts or infections
- ✓Minimize exposure to environmental allergens — keep the home clean and well-ventilated
Treatment Options
Commercial Tear Stain Removers
Products like OcuBright or Angel Eyes can help fade existing stains. Always use products specifically designed for use around dogs' eyes. See our Amazon Favorites for recommendations.
Warm Water and Soft Cloth
For mild staining, gently wiping the area daily with a warm, damp soft cloth can help. Use cotton rounds (we recommend ForPro cotton rounds — see our Amazon Favorites) for gentle application.
Saline Solution
Sterile saline contact lens solution (without preservatives) can be used to gently flush the eye area. This is safe and soothing for mild irritation and daily maintenance.
Address the Underlying Cause
Treating the symptom alone won't solve chronic staining. Work with your veterinarian to identify and address the root cause — whether dietary, anatomical, or health-related.
"Tear stains can take time to fade, especially if they are long-standing. Be patient and consistent with your prevention routine — you should see improvement within a few weeks."
When to See a Vet
If tear staining is sudden, severe, accompanied by discharge, or your dog appears to be in discomfort, please consult your veterinarian. These could be signs of a blocked duct, eye infection, or other condition that requires medical treatment.
