My 1800 pound Belgian gelding has DSLD. He has difficulty getting up from a prone position. He developed a hock sore, and after trying many different items to cover his pressure sore, I ordered the hock shields. It is hard finding items large enough for him, but these covers were perfect. They were shipped SUPER fast, thank goodness, and the quality is amazing. I wash them in my washing machine and they come out like new every time.
