For years my 20 year old has developed hock sores off and on. Because of his age, and arthritic changes that have increased, he now lays down much more, and the last year, his hock sores were becoming troublesome to get ahead of. They were struggling to have any healing time between bouts. Then I found your hock shields. They have been a literal lifesaver. The hair is almost completely grown back on his hock, and you can tell that it has alleviated a portion of his discomfort. THANK YOU SO MUCH for this ingenious product. We will be forever grateful, as I'm sure it has contributed to allowing us to have more days with our special boy.
