(S&M Nutec) Greenies Dental Dog Treats give your dog cleaner teeth with every chewy and delicious bite. Greenies come in distinct sizes and textures to match the chewing action of all dogs. Some dogs have a great deal of jaw strength and some don't, so Greenies dog treats match the size of the dog. The chewy texture allows teeth to sink in and clean teeth while controlling plaque and tartar buildup. Greenies dog treats are made with vitamins, minerals and soluble proteins that provide 100% digestibility in the gastrointestinal tract.
