Vetoquinol Dentahex Oral Care Chews with Chlorhexidine for Dogs Large (18 oz) After your pet finishes a meal, tiny food particles combine with bacteria to form plaque. Plaque, if not removed, eventually hardens into calculus or tartar, and can ultimately lead to periodontal disease. If left untreated, periodontal disease is the single greatest cause of health problems in pets. Regular veterinary checkups and professional "dental cleanings" are an important first defense in controlling and preventing periodontal disease. Routine home dental care is equally important in helping keep your pet and its teeth healthy. Simply brushing food debris and plaque from the teeth and gumline can greatly reduce the chance of tartar buildup, periodontal disease, and bad breath. Dentahex Oral Care Chews are coated with Chlorhexidine gluconate. Chlorhexidine, along with the natural abrading action of beefhide, helps to remove plaque and prevent the buildup of tartarforming bacteria. Remember, your pet depends on you and your veterinarian for all its health care. Ask your veterinarian about the many different home oral care options available to you.
