Two years ago my oldest alpaca, Siobann, became very sedentary. She also seemed to show pain and stiffness when standing up. I asked my veterinarian about glucosamine and she recommended Holistic Horse. Siobann has been getting the Glucosamine Powder for Llamas and Alpacas in her grain every night. She no longer shows any signs of discomfort and goes out in the field with the herd. I think she is remarkable for a nineteen and a half old girl thanks to glucosamine!
