I have been giving Liquid-Vet to my collie cross (Sable 13.5 yr old, 50 lbs) who has started to show problems with her hips. She’s had 1 small bottle and 1 large bottle now. I tried using other joint products but they did not make a difference. I really didn’t like seeing her struggle. She still has a lot of “puppy” in her but when she was in pain, she didn’t bounce around or seem happy. Since starting her on Liquid-Vet, she got her “puppy” bounce back. I’m so happy to see. She tires easily so doesn’t play for as long but at least now she is back to playing!
