My labradoodle Rose is eight years old. I knew down the road that there would joint problems. I have five dogs and by watching my clan run up north I could see her running very stiff legged. After giving her Liquid-Vet for nearly a month, what a fantastic product! She is much looser and she is running like a puppy. Thank you! I also have Lhasa Apso mix. Early this year she had some joint pain and after seeing my vet she suggested Liquid-Vet. She is over ten years old what a difference, like a new dog. I am going to start giving Liquid-Vet to all of them!
