I have an 18 hand 1800 lb Belgian draft horse and we have always struggled with hock sores. It's insanely frustrating because I have tried literally every thing you can imagine. I even went as far as using surgical glue, to glue a strip of neoprene over the sore because no wraps would stay on. I spent hundreds of dollars on medicine and wraps, all to no avail. I felt horrible and didn't know what to do. When I got the hock boot I was immediately impressed with the simplicity of it. The best part was, it actually stated on! For the first time I had a product that actually stayed on and the healing could begin. Over 2 months the wound went from being about 3 inches wide to the size of a quarter. Now it is completely healed, I keep them on now as a preventative measure. It is the most important piece of medical equipment for my horses I own. Thank you soooo much for making this amazing product!
