How to prevent tear stains on dogs?

Tear stains—those reddish-brown streaks under a dog’s eyes—aren’t just unsightly; they can signal irritation or even health issues. Breeds with big, round eyes like Shih Tzus or Pugs are more prone, but any dog can develop them if their tear ducts get blocked or irritated. The good news is, with consistent care, you can keep those stains at bay.

Start with daily grooming. A quick wipe with a damp, soft cloth—think microfiber, gentle on sensitive skin—can remove excess moisture before it dries and discolors fur. For dogs with long hair around the eyes, like Lhasa Apsos, trimming those strands prevents them from poking the eyes and triggering extra tearing. Just be careful with scissors; a rounded-tip grooming tool is safer for wiggly pups.

Diet matters more than you might think. Cheap kibble with artificial dyes or high levels of grains can cause excess tearing in some dogs. Try switching to a formula with natural ingredients—look for labels that list real meat as the first ingredient. Adding a splash of filtered water to dry food can also help, as dehydration sometimes worsens tear production. Always check with your vet before changing diets, especially in places like the UK where pet food regulations are strict.

Keep an eye on water quality. Tap water with high mineral content, common in areas with hard water, can irritate some dogs’ eyes over time. Using a water filter or providing bottled water might make a difference, especially if you notice your dog drinking less or rubbing their face more after sipping from the bowl.

Air quality plays a role too. Dust, pollen, or smoke can irritate eyes, making tears flow more. In cities like Paris or New York, where air pollution spikes in winter, running an air purifier near your dog’s bed can cut down on irritants. Just be sure to clean the filter regularly—clogged filters do more harm than good.

Don’t ignore persistent stains. They might mean blocked tear ducts or infections, which need vet attention. In many European countries, like Sweden, neglecting a dog’s visible health issues could violate animal welfare laws, so staying proactive isn’t just kind—it’s legally smart. Your vet might recommend special eye drops or, in rare cases, a minor procedure to unclog ducts.

Consistency is key. A five-minute daily routine—wipe, trim, check—goes further than occasional deep cleans. Watch for changes: sudden redness, swelling, or excessive tearing could mean something’s wrong. With a little effort, your dog’s eyes will stay bright, and their face will stay stain-free, keeping both of you happy.
