PT my gray mare has a dropped hip but I noticed yesterday that she isn't bending her back right hock when she walks. I am wondering if there is anything that I can do for her. I am also asking my vet about this as this used to be her horse that she wanted to find a good home for. She has had her since she was a yearling. I flexed her hock yesterday and she walked off just fine. I am also looking into a good supplement for her but should I use something for the joints or something more that pertains to the legs and more specifically the hock area. Thanks guys for the info.
