It's a pretty common sight, especially in breeds like Maltese, Bichon Frise, and Poodles.

But what causes these stains, and should you be worried?

Both are caused by porphyrin — a pigment found in your dog's tears and saliva. 

When it builds up on light-coloured fur, it leaves reddish-brown marks.

1. Excessive tears (Epiphora)
   Some dogs — especially small breeds with short noses and shallow eye sockets — produce a lot of tears. When those tears don't drain properly, they sit on the fur, creating the perfect environment for staining.

2. Frequent licking
   If your dog constantly licks their paws or body, their saliva can stain the fur in those spots. This often happens when they're itchy from allergies or feeling anxious.

3. Yeast and bacteria
   Moist areas, like under the eyes or around the paws, are breeding grounds for yeast and bacteria. A type of yeast called Malassezia thrives here, darkening the stains even more — often with a funky smell.

4. Diet and water
   Hard water (with lots of minerals) or iron-heavy diets can intensify the stains. Food allergies or poor-quality food can also contribute.

• Eye infections
• Allergies
• Blocked tear ducts

If the stains come with redness, swelling, or discomfort, it's time to visit the vet.

1. Clean regularly 
   Use pet-safe wipes or a soft cloth with warm water to gently clean the stained areas daily. For tear stains, you can also use saline solution (just like the kind humans use for their eyes).

2. Grooming is key
   Keep the fur around the eyes trimmed short. This prevents tears from soaking into the fur and reduces staining.

3. Filtered water
   Switch to filtered or distilled water instead of tap water to reduce mineral intake. Over time, this can help minimise staining.

4. Improve their diet
   A high-quality, grain-free diet can make a big difference. Some dogs are sensitive to grains, which can increase tear production and staining.

5. Try tear stain removers
   There are vet-approved products designed specifically to reduce staining. Be sure to choose one that's safe and gentle for your pup.

6. Check for allergies
   If your dog licks their paws a lot, it might be due to allergies. A vet can help identify what's triggering the itchiness.

With regular cleaning, a good diet, and some extra care, you can help keep your dog's coat looking fresh and bright.

If you're ever unsure, don't hesitate to check with your vet — it's always better to be safe than sorry!
