Greenies have been specially designed with our dog's teeth in mind. The first treat to receive the Veterinary Oral Health Council (VOHC) Seal of Acceptance for control of plaque and tartar buildup. They were designed by a  board-certified veterinary nutritionist and other experts to develop the first toothbrush-shaped dental treat. Cleans faster and easier than a toothbrush, Greenies are easy to digest and made from highly soluble proteins. The perfect treat that cleans their teeth at the same time!
