My boy Zach had a hip/leg injury when he was young. I adopted him when he was 3 yrs old and always was slow getting up and started after laying for a while. He got to where he would jump or run when playing. I started the awesome Liquid-Vet chicken flavor about a year ago, and he likes it on his food no problems getting him to eat it. The response from the Liquid-Vet is..hes running again and he doesn’t hesitate to jump. Even spoke with Jonathon and was super nice and really took the time to explain the product and didn’t act like he didn’t have time to talk. If your pets have hip problems…BUY IT you won’t regret it…it isn’t a 1 day fix just keep regular doses and it will show its magic in your pet.
