We have been using SierraSil Pet Chews for our Sheltie, Sadie. She is now 13 years old and has stiffness from age and exercise. Since using SierraSil daily for the last 2 years, Sadie has improved dramatically and seems to be in less discomfort. She plays, sleeps and gets around much better. Thank you SierraSil!
