Heiro for horses is a great product. I see they now have a dog formula. Reviews are questionable for bad hips and arthritis.
I’m always on the search for some new miracle for my 8 yr. old GSD who’s starting to limp after
an active day. Sure she has hip displasia and hind end arthritis due to poor conformation.
Right now Dasuquin w/ msm and Lubrisyn are our go to.
