Was picking out my horse's hoof when my pick got stuck. Cleaned it with a wire brush and saw a chunk of what seems to be the sole hanging on. That trench along my horse's hood wall is due to an abscess she had, but is it really supposed to be that large and deep? I've been putting Absorbine Thrush Remedy on it to try and prevent anything but I don't know if it's working. She's getting trimmed tomorrow but I was wondering what other people think too. Her sole is peely and chalky from the moist ground. She's outside 24/7 and her diet is pasture only.
