Bests & Worsts Reviews from Amazon

I have 3 dogs ranging in age of 2 years old to 15+ years old. I started this on Wednesday night for all 3 dogs. By yesterday Noah who is 15+ years old and stays inside, hasn't had a fall or stepped on anything can't walk this morning. He is actually not putting weight or press on his back leg. My youngest dog Mae has no energy and is sick. So I would not recommend this product. If I could have given it no stars I would have.
