Delilah hurt her hoof. It happened sometime when I had the goaties out of their pens today...I have no idea how she did it and only noticed when I saw blood in the snow. I put her on the milk stand so I could clean it up and examine the foot. It appears that she somehow "sliced" about a 1/4" section of the outer wall of her hoof off. There's literally a vertical chunk of the hoof wall--from the ground to her hair line--missing. It was not bleeding too badly...and thankfully does not seem to be causing a lot of pain. She is not limping and was running and playing like normal. So, other than keeping it as clean as possible, is there anything else I can or should do for this type of injury?
