Angels’ Eyes for Dogs helps treat the reddish-brown marks on or around your dog’s eyes, often called tear stains. Tear stains are common in many light colored dogs and certain breeds are inherently more likely to develop them, such as the Maltese. Angels\' Eyes for Dogs is rich in either chicken or beef liver and the mild antibiotic tylosin tartrate, shown to eliminate the bacteria that causes tear stains in as little as one month. The two types of bacteria responsible for tear staining include Ptyrosporin and Porphyrins, and can be present in dog tears and saliva. Because they are present in saliva, your dog may get these same reddish-brown marks on or around his/her mouth as well. Tylosin tartate fights these two types of bacteria and helps to restore a normal, healthy-looking coat around your dog’s eyes and mouth.
