If you own a Bichon Frise, you have likely noticed reddish-brown streaks under their eyes. These are tear stains, and they are very common in this breed. The direct answer: tear stains form when tears overflow onto the fur, and the iron-containing porphyrins in the tears oxidize when exposed to light, creating a red-brown discoloration. In Bichons, their prominent eyes, shallow eye sockets, and frequent tear production worsen the issue. While not usually a health problem, stains can indicate underlying issues. Here is how to manage them.

Understanding What Causes Tear Stains in Bichon Frises

Tear stains are primarily cosmetic, but their root cause involves several factors:

  • Porphyrins: These are natural byproducts of red blood cell breakdown, excreted through tears, saliva, and urine. When porphyrins accumulate on fur and are exposed to sunlight, they turn reddish-brown. White-coated breeds like the Bichon Frise show stains dramatically.
  • Epiphora (excessive tearing): Bichons often have eye drainage issues. Their brachycephalic (flat-faced) structure can cause shallow orbits and abnormal tear drainage. Blocked or narrowed tear ducts (nasolacrimal ducts) also contribute.
  • Teething: In puppies, teething can stimulate tear production. Stains often decrease after adult teeth come in.
  • Diet and Water: Low-quality food with additives, artificial colors, or high mineral content can worsen stains. Tap water with high iron or minerals may darken stains.
  • Yeast or Bacteria: Reddish-brown stains can also be caused by Malassezia yeast or bacteria, which thrive in moist environments. This requires veterinary treatment.

Step-by-Step Guide to Reducing Tear Stains

1. Keep the Eye Area Clean and Dry

  • Daily wipe with a warm, damp cloth or a dedicated pet wipe. Dry thoroughly afterward.
  • Trim the fur under the eyes short to minimize tear contact with hair. Use blunt-ended scissors or visit a groomer.
  • Use a stainless steel or glass water bowl (plastic bowls can harbor bacteria and exacerbate stains). Wash bowls daily.

2. Review Diet and Water

  • Opt for a high-quality dog food with limited ingredients, free of artificial colors and fillers (like corn and wheat). Some owners find a grain-free or limited-ingredient diet helps.
  • Add a probiotic supplement formulated for tear stains (look for those containing Lactobacillus acidophilus or other beneficial bacteria). Research suggests these can reduce porphyrins.
  • Switch to filtered or distilled water. Tap water may contain minerals that darken stains.

3. Check for Allergies and Eye Health

  • Common allergens: food (beef, dairy, chicken), environmental (pollen, dust), or contact (shampoo). If your Bichon shows itchiness, ear infections, or digestive upset, consult your vet about allergy testing.
  • Eye problems: chronic tearing may stem from conjunctivitis, dry eye (keratoconjunctivitis sicca), or eyelash abnormalities (distichiasis). Have a vet examine the eyes to rule these out.

4. Use Tear Stain Removal Products Wisely

  • Many commercial wipes or powders contain antibiotics (like tylosin) or mild bleaches. Use with caution and only under veterinary guidance. Overuse may irritate eyes or cause resistance.
  • Home remedies like coconut oil or cornstarch can be applied sparingly to dry the area, but they do not address the underlying cause.

When to See a Veterinarian

Consult a vet if:
– Stains appear suddenly or are accompanied by redness, swelling, discharge, or squinting.
– Your Bichon scratches at the eyes or face.
– You notice a foul odor or greenish discharge, which may signal infection.
– The stains persist despite good hygiene and diet changes.

Your vet can perform a Schirmer tear test to check for dry eye, fluorescein stain to detect corneal ulcers, and flush the tear ducts to clear blockages. For suspected yeast or bacterial infections, they may prescribe medicated wipes or ointments.

Preventative Measures for Long-Term Control

  • Regular grooming (every 4-6 weeks) to keep facial hair short.
  • Use a harness instead of a collar to reduce pressure on the neck and eyes.
  • Consider adding a daily eye wash formulated for dogs to flush debris.
  • Feed a balanced diet and avoid table scraps.
  • Keep your Bichon’s face dry after baths; use a low-noise blow dryer on cool setting.

While tear stains may never disappear completely, consistent care can make them barely noticeable. Focus on underlying health first, then cosmetic management.

Key Takeaway

Focus on keeping the eye area clean and dry, improve diet and water quality, and consult a vet if stains worsen or other symptoms appear.
