Reason for New Release of Trial 5g Size

The first step with a tear stain supplement is whether your dog or cat will eat it.

It allows those who have started to notice tear stains to try it easily as a first step.

Reasons Why It's Chosen by Owners Concerned About Dog Tear Stains

This product is a natural food featuring raw enzymes derived from fermented koji, using rice bran, rice malt, and koji mold as its main ingredients. It is completely additive-free, using no artificial additives, colorings, fragrances, or preservatives. Domestic, organic, and human-grade raw materials are carefully selected, with a focus on non-oil coating and full ingredient disclosure.
