That's why Exclusive(R) Chicken & Rice Formula Senior Dog Food is formulated with Glucosamine and Chondroitin Sulfate, a natural nutrition combination that helps maintain normal healthy joints. Also, older dogs may lose some ability to digest and absorb nutrients as they age. Exclusive(R) Chicken & Rice Formula Senior Dog Food is designed to supply high nutrient levels. We even made the shape of the kibbles easier for senior dogs to grasp and chew. No wheat, soy or fillers. | Exclusive Signature Senior, Chicken and Brown Rice Formula Dry Dog Food | Size 30 lbs
