How to Remove and Prevent Tear Stains on Dogs

Tear stains are those reddish-brown streaks that run from the inner corner of a dog’s eyes down their muzzle. While especially visible on light-colored dogs, all dogs can develop them.

What Causes Tear Stains?

Porphyrin

The main culprit is porphyrin, a pigment in tears, saliva, and urine that turns reddish-brown when exposed to air and sunlight.

Excessive Tearing (Epiphora)

Causes include:

Blocked tear ducts
Eye irritation or infection
Allergies
Shallow eye sockets (brachycephalic breeds)
Entropion (inward-rolling eyelids)
Hair growing into eyes

Other Factors

Genetics
Diet
Water quality (high mineral content)
Teething in puppies
Yeast or bacterial infections

Breeds Prone to Tear Stains

Maltese
Bichon Frise
Shih Tzu
Poodles
Cavalier King Charles Spaniels
Pugs

Pomeranians

Removing Existing Stains

Daily Cleaning

Use a warm, damp cloth to wipe under eyes
Dry thoroughly (moisture breeds bacteria)
Use a flea comb to remove debris

Tear Stain Removers

Commercial tear stain products
Colloidal silver solution
Diluted hydrogen peroxide (carefully, avoid eyes)
Coconut oil (natural antibacterial)

Professional Grooming

Groomers can safely trim stained fur and recommend products.

Prevention Strategies

Keep the Area Dry

Wipe eyes 2-3 times daily
Trim hair around eyes
Use a small amount of cornstarch to absorb moisture

Address Diet

Feed high-quality food
Use filtered or bottled water
Avoid food with artificial dyes
Consider adding probiotics

Maintain Hygiene

Keep facial fur trimmed
Wash food and water bowls daily
Regular grooming appointments

Address Health Issues

See your vet if staining is sudden or severe to rule out:

Eye infections
Blocked tear ducts
Allergies

What to Avoid

Antibiotics without vet supervision
Harsh chemicals near eyes
Bleach-based products
Ignoring underlying conditions

Realistic Expectations

For genetically prone breeds, tear staining may never completely disappear, but consistent care can significantly reduce it.
