Tear Stain Soft Chews are palatable oral chews intended for dogs and cats age 12 weeks and older. Each chew delivers a blend of cranberry extract, Oregon grape root, vitamin C, eyebright herb extract, marshmallow root, lutein, and omega-3 and omega-6 fatty acids from flaxseed. The formula is designed to help lubricate mucous membranes and support the immune system, working toward reducing and preventing tear staining around the eyes. Dosage is based on body weight, ranging from one chew daily for smaller pets up to several chews daily for larger dogs. The chews are typically given daily until staining subsides, then continued for a further period before tapering to as-needed use, with visible results generally taking several weeks. The product is produced in the United States in a cGMP compliant facility and is packaged as a count of soft chews per container.
