I have had great luck with The yorkie royal canine food. I know that many here have stopped it for one reason or another. Bella loves it. Her coat is shiney..no dandruff..no problems with her stool. This food contains joint support. My vet also says walking your dog up hill will strenthen the tendons ligament and muscles to help prevent the knee cap from slipping out. It tightens everything up. We dont have hills in FL so I use the incline on the treadmill |
