The Veterinary Oral Health Council (VOHC) has awarded its Seal of Acceptance to Greenies Dental Chews for both plaque and tartar control. The Seal of Acceptance is given only to products meeting the VOHC’s strict requirements of demonstrated efficacy in controlling plaque and/or tartar build-up. Greenies dental chews are 100% edible which means that there isn't anything in it that your dog can't eat and enjoy! Highly Soluble Greenies dental chews are easy to digest and highly soluble (that means that they break down easily in the digestion process). The key to solubility lies in the proteins used to make the product. Greenies use 4 high-quality, easily digested proteins as the building blocks of this chewy recipe: Gelatin Wheat protein isolate Soy protein isolate Sodium caseinate This protein combination gives Greenies its irresistible chewiness and is the reason why the product will break down quickly in your dog's digestive system. In a simulated digestion test, a whole petite Greenies dental chew was reduced to absolute mush! 95.7% Digestible Greenies dental chews are 95.7% digestible - that's more than your average dry dog food (80-85%). That means that your dog's body can easily absorb and use all those good vitamins and minerals that have been added to the formula! Breaking Up Is Easy to Do Not only does the toothbrush have more nooks and crannies to clean teeth, it also has more natural break points to help a dog naturally chew it into small, easily-digested pieces. It's All in the Chew Last but not least, you can see how chewy the Greenies dental chew is. This chewy texture actually makes it easier for dogs to lovingly gnaw Greenies dental chews into delicious little bits that are easy to swallow and digest.
