The Truth About Tear Stains and How to Treat Them

Tear stains in dogs are usually caused by excess tear production, facial structure, or mild irritants — and they can be treated with gentle grooming, dietary tweaks, and vet-approved products. Always rule out underlying health issues first.

🐶 The Truth About Tear Stains and How to Treat Them

Those reddish-brown streaks under your dog’s eyes might look harmless, but they can signal more than just cosmetic concerns. Tear stains are common in many breeds, especially those with light-colored fur or flat faces — and while they’re often benign, they deserve attention.

🧬 What Causes Tear Stains?

Tear stains form when porphyrins, compounds found in tears and saliva, oxidize on the fur. Common causes include:

• Excess tear production (epiphora) due to blocked tear ducts or eye shape

• Allergies or irritants like dust, pollen, or smoke

• Facial anatomy, especially in flat-faced breeds like Shih Tzus and Bulldogs

• Diet and water quality, including food sensitivities or minerals in tap water

• Ear infections or ingrown eyelashes, which can increase tearing

• Underlying conditions like conjunctivitis or glaucoma — these require vet attention

🧼 How to Treat and Prevent Tear Stains

1. Daily Grooming

• Wipe the area with a damp cloth or vet-approved tear stain wipes.

• Keep fur trimmed around the eyes to reduce buildup.

2. Improve Water Quality

• Use filtered or distilled water to reduce mineral staining.

3. Adjust Diet

• Switch to high-quality, limited-ingredient food if allergies are suspected.

• Avoid artificial additives and fillers.

4. Try Tear-Stain Removers

• Look for products with natural ingredients like coconut oil or colloidal silver.

• Choose vet-approved brands — avoid harsh chemicals.

5. Rule Out Medical Issues

• If stains worsen or are accompanied by discharge, swelling, or discomfort, consult your vet.

• Conditions like glaucoma or infections need professional care
