Why Do Dogs Tear?
Tear staining occurs when tears overflow from the eyes onto the fur. The reddish-brown color is caused by porphyrins, naturally occurring iron-containing molecules produced when the body breaks down red blood cells. Porphyrins are excreted through tears, saliva, and sweat. When porphyrin-rich tears sit on white or light-colored fur, exposure to light and oxygen turns the pigment brown or red.
Common Causes of Excessive Tearing
Food Allergies & Intolerances
Sensitivities to specific protein sources (like chicken or beef), artificial preservatives, or low-quality fillers can trigger systemic inflammation, leading to hyper-active tear glands.
Stress & Environmental Factors
Environmental stressors, routine changes, or exposure to irritants like household cleaners, smoke, or dust can increase tear production.
Anatomy & Breed Predisposition
Flat-faced breeds or toy breeds often have shallower eye sockets or narrower tear ducts. This prevents tears from draining normally into the nasal cavity, causing them to spill over onto the face.
Blocked or Narrow Tear Ducts
Infection, inflammation, or developmental quirks can block the nasolacrimal ducts, preventing standard tear drainage.
Dietary Minerals & Tap Water
High mineral content in unfiltered tap water (iron, magnesium, or calcium) can intensify porphyrin staining.
Ingrown Eyelashes or Hair Irritation
Hair around the eyes or misdirected eyelashes (distichiasis) rubbing against the cornea continuously stimulates tear production.
How to Prevent and Treat Tear Staining
1. Daily Hygiene Routine
Clean the Area Daily: Wipe the under-eye area gently twice daily using a warm, damp washcloth or specialized, vet-approved eye wipes.
Keep Fur Trimmed: Safely trim long facial hair around the inner corners of the eyes to prevent moisture trap and physical irritation.
Keep the Face Dry: Moisture creates an ideal environment for yeast and bacterial growth, which darkens stains and causes odor. Gently pat the area dry with a tissue after cleaning.
2. Dietary Adjustments
Switch to Filtered Water: Offer purified or bottled water instead of tap water to reduce mineral buildup in tears.
Review Food Ingredients: Switch to high-quality whole-food diets free from artificial dyes, cheap fillers, and common allergens.
Use Stainless Steel Bowls: Plastic bowls can harbor bacteria and microscopic scratches that irritate a dog's face while eating or drinking. Switch to stainless steel, ceramic, or glass.
3. Stress & Environment Management
Keep dust, smoke, and strong aerosol sprays away from your dog's living spaces.
Maintain a consistent routine to keep stress levels low.
When to See a Veterinarian
While tear stains are usually harmless, contact a veterinarian if you notice any of the following symptoms:
Squinting, rubbing, or frequent blinking
Cloudiness, redness, or swelling in or around the eyes
Thick yellow or green discharge (indicating a bacterial infection)
A foul odor coming from the eye region
