If you own a Bernese Mountain Dog, you have likely noticed reddish-brown streaks below their eyes. These are tear stains, and while they are not dangerous, they can be unsightly and sometimes indicate an underlying issue. Tear stains form when tears overflow onto the fur and the iron in tears oxidizes, creating a rusty color. This is more visible on white fur, which Berners often have around their eyes. The main reason Bernese Mountain Dogs get tear stains is their facial structure. They have a short muzzle and deep-set eyes, which can cause tears to spill onto the face rather than draining properly. Additionally, some Berners have hair growing inward near the eyes, irritating the cornea and causing more tears. Allergies are another common cause. Bernese Mountain Dogs can be allergic to environmental triggers like pollen, dust, or certain foods. Allergies cause inflammation and increased tear production. Blocked tear ducts can also lead to tear overflow. In puppies, the tear duct opening may be small or temporarily blocked. In older dogs, scars or debris can cause blockages. Genetics play a role, too. Some lines of Bernese Mountain Dogs are more prone to excessive tearing. While tear stains are often a cosmetic issue, they can sometimes signal an infection or eye problem. If the staining is accompanied by redness, swelling, discharge, or squinting, consult a veterinarian. For most dogs, tear stains can be managed with regular cleaning and addressing underlying causes. Here is how to reduce and prevent tear stains in your Berner.
Keeping the Eye Area Clean
The first step is daily cleaning. Use a soft, damp cloth or a vet-approved eye wipe to gently wipe under the eyes each morning and evening. This removes excess tears before they can oxidize. You can also use a warm saline solution (1/4 teaspoon salt in 1 cup distilled water) to gently flush the area. Pat dry with a clean cloth. Be careful not to touch the eye itself. Some owners use a fine-toothed comb to gently remove any dried crust. Avoid using scissors near the eyes; if hair is irritating, have a groomer trim it. Regular grooming is essential. Keep the fur around the eyes short to prevent tears from wicking onto the hair. You may also consider changing your dog’s water. Some believe tap water with high mineral content contributes to stains, so filtered or distilled water might help. While this theory is not proven, it is a harmless change to try.
Addressing Allergies and Diet
Allergies are a major cause of tear stains. If your Berner has seasonal allergies, talk to your vet about antihistamines or other options. For food allergies, consider a limited ingredient diet or a novel protein source. Some dogs react to chicken or beef. A diet rich in omega-3 fatty acids can reduce inflammation. You might add a fish oil supplement after checking with your vet. Probiotics can also support immune health. Some owners report that removing certain treats or additives (like artificial colors) reduces staining. Be patient; diet changes can take 4-8 weeks to show results. Also, ensure your dog is not drinking from plastic bowls, which can harbor bacteria and cause chin acne, but this is less related to tear stains.
When to See a Veterinarian
If you notice any of the following, schedule a vet visit: thick, yellow-green discharge; red or swollen eyes; your dog squinting or pawing at eyes; sudden increase in tears; or if tear stains have a foul odor. These could indicate an eye infection, blocked tear duct, or other medical issue. Your vet can perform a tear test, check for blocked ducts, or prescribe antibiotic ointment. In rare cases, a procedure to open blocked ducts may be needed. Do not use over-the-counter stain removers without vet approval, as some contain antibiotics or chemicals that can cause irritation. For persistent, purely cosmetic stains, your vet may recommend a special stain-removal product or a treatment like oral medication (e.g., tylosin powder) that helps reduce stain-causing bacteria. Always follow your vet’s advice.
Final Thoughts
Tear stains are a common issue in Bernese Mountain Dogs due to their facial structure and genetic predisposition. While usually harmless, they can be managed with regular cleaning, grooming, and addressing allergies or infections if present. Work with your vet to rule out medical problems, and keep the eye area clean and dry. With consistent care, you can minimize those rusty streaks and keep your Berner looking their best.
Key Takeaway
Consistent daily cleaning and addressing underlying allergies or eye issues are the most effective ways to manage tear stains in Bernese Mountain Dogs.
