What Causes Dog Eye Stains?

Causes of Red Yeast Fur Staining and Dog Eye Stains?

The truth about tear stains ! The truth is we really shouldn’t even call it “Tear Stains”

Facial Fur Staining - Tear Staining

Tear Staining, or it’s proper name Epiphora, is defined as an overflow of tears onto the face, but that is actually a horrible definition of the actual problem and it’s root causes. First, red or brown tear staining is not just limited to the area right beneath the eyes, so that is a misleading term. A better term for this “disorder” would be Fur Staining or Red Yeast Fur Staining, as many parts of the animals fur can be affected, including; the area beneath the eyes, the beard and mouth fur, even the fur on the paws can stain from excessive licking. So as you can see “Tear Staining” is a very poorly defined and named term.  Tear stains, or red yeast fur staining, can be brought on by many underlying factors; including:

  • The diet you feed your pet. Usually diets to high in grains can cause allergies and then excessive tearing and bacteria growth in the digestive tract.
  • Overall Health: Digestive upset, allergies, virus, even a cold.
  • Breed predisposition. Do you have a breed that has many skins folds, or shallow tear ducts, or is prone to digestive upset.
  • Shallow tear ducts or breeds with pushed in faces and shallow sinus.
  • Medical conditions such as Entropian or Cherry eye can cause excessive tearing. Even just a few hairs rubbing the inside of the eye can cause tears.
As you can see there are many reasons for red yeast tear stains. Even the best made products can not fix medical or physical problems with the eye, such as Entropian or shallow tear ducts.
Changing the environment that Red Yeast likes to grown in, making it in-hospitable to the growth of red yeast, changing the pH balance and bad bacteria vs. good bacteria ratio in the digestive system,seems to be the safest and best long term solution to tear and fur staining.
