Tear staining begins with excess tearing, a complication in some breeds which is more than likely genetic. When the area around the eyes becomes damp it creates a breeding ground for bacteria and yeast. The most common yeast infection is Ptyrosporin, also known as Red Yeast, which causes staining as well as a slight odour.
Once a ptyrosporin infection begins it can eventually cause an oral infection. The most common evidence of an oral yeast infection is red staining on areas that are not naturally wet, but are often licked, like the paws and sides of the mouth.
Tear Stain Away contains an active mild antiseptic derived from coconut oil which acts on the bacteria and fungus that cause the stain and an active anti bacterial / anti fungal agent which breaks down red yeast. Used daily until the staining has completely faded, it will leave your furry friend looking happy!
