More than anything, the weight loss will be of enormous help! My Cody was dx with hip dysplasia at age 3 and developed bad arthritis in one hip by age 5. She was never overweight, but even so, the vet suggested she lose 5 lbs. to lessen the strain on her joints; she very active and loves to run! She's also on a glucosamine/kelp supplement rx by the vet and that along with regular, non strenuous exercise and keeping the wt. down, has worked wonders! I'm sure an over the counter glucos. supplement would be just as effective as the one my vet prescribed! Keep up the good work Duke and before long, you'll be doing great Sandra
