ProDen PlaqueOff Dental Care Bones are shaped, chewable treats meant for daily use in a dog's oral care routine. Each bone is built around dried potatoes and other natural ingredients along with A.N ProDen kelp, a naturally sourced ingredient associated with oral care support. The bone's shape is designed to work through chewing action, helping to physically work against the teeth surface as the dog gnaws. Bones come packaged in a resealable bag and are scored so they can be broken in half for smaller dogs. The amount fed is based on the dog's body weight, with smaller dogs receiving a half bone and larger dogs a full bone each day. The formula is made without grain ingredients and is manufactured in the United States. Fresh water should be available whenever the chew is offered.
