Regular Size Dental Bone A line of Dental bones specifically designed to reduce the incidence of peridontal problems for dogs. Dental Chews are made from a plastic material that is softer than other Nylabone nylon products. These chews are intended for use by dogs that are soft and average (not aggressive). By massaging gums and helping to remove plaque, these bones reduce the incidence of peridontal problems, resulting in a healthier mouth and fresher breath.
