Greenies Blueberry Flavour Large Dog Dental Treats are made from highly digestible, balanced ingredients, fortified with added vitamins, minerals and taurine. The chewy and flexible texture allows your dog's teeth to sink in right up to the gums without crumbling for more effective plaque removal. They are also designed with a unique shape designed to maximise cleaning effectiveness. When fed daily, Greenies Dental Chews for dogs are scientifically proven to reduce plaque and tartar build-up, freshen breath and maintain healthy gums and have been awarded the Veterinary Oral Health Council (VOHC) Seal of Acceptance for plaque and tartar control.
