Angels' Eyes® is a revolutionary product that is created to eliminate unsightly tearstains (epiphora) from your dog or cat's eyes, which can sometimes be irritating. The product is also used to reduce or completely eliminate staining around your dog’s mouth and coat as a result of licking. The greatest feature of this product is its ability to work before the tearstains can even start to accumulate around your dog’s eyes. This product contains essential and safe elements such as protein, fats and fibers, with 100% pure chicken liver, beef, or sweet potato. The active ingredient in Angels' Eyes®, Tylosin as Tartrate, will prevent your dog from contracting Ptyrosporin (Red Yeast) and bacterial infections which causes excess tearing and staining. Tylosin binds with Porphyrin pigments and prevents them from binding with the animals hair. The amount given to the dog depends on their age and weight. While this product is safe for pregnant dogs, they are not recommended to puppies until they are six weeks old.  Angels' Eyes® is proven 100% safe for dogs and cats. There are no reports of toxicity with long term use and Angels' Eyes® is safe short term even if overdosed..
