My older dogs are on this. One has high liver enzyme levels and cannot be on nsaids. He began limping all the time and had moderate pain. He takes Phycox already. But, vet wanted him to also start Movoflex in addition. It takes about a month for the full effects to show, so do not expect immediate results. My dog saw results in about 3 weeks. He rarely ever limps and doesn’t wait for me to go up/down stairs. I have to get to him before he goes up/down them now. My other older dog is also on this. His front leg joint issues are severe and the supplement is not enough. He is on Movoflex, Phycox, and Metacam. It helps, just not enough because his joint pain is severe. This product works well for dogs with mild to moderate joint issues/pain. So, if your dog is having joint pain/issues, this product works pretty well. It is well worth a try.
