I just wanted you to know that Liquid-Vet has worked amazingly well on my 17 yr old Australian Shepherd. She’s up on the sofa for the first time in 4-5 years, about a month after starting. ‘Burying’ her bone behind the cushions used to be a daily occurrence for her most of her life, so it was a big shock to find her on the sofa after so many years of being physically unable to do it. I also like that it’s manufactured here in the US. Thanks for the great, affordable product. I may well buy the horse version next!
