My gelding does not have the best hooves. It is mainly his front hooves that are easily cracked and chipped. And a few months ago he had an abscess that left a crack 3" long. I need to get him on a hoof suppelment. What is a good and affordable hoof supplement I already have him on a joint supplement so I am only looking for hoof supp. I saw Jeffers has a hoof supp that's pretty affordable. What are the main ingredients that I need to be looking for I know biotin is one of them. Thanks in advance any advice is very welcome.
