GREENIES® Hip & Joint Care Canine Dental Chews help clean your dog's teeth and support a lifetime of healthy joints. They feature natural sources of glucosamine and chondroitin from New Zealand green mussels and chicken cartilage to help support mobility. When fed daily, these treats also help fight tartar buildup, control plaque and freshen breath. They're designed for dogs of all ages, but have a softer texture that's ideal for older dogs. Give your dog dental health and joint care in one delicious chew.
