Of course your horse will technically be barefoot if you take the shoes off, but having a healthy, sound barefoot horse is a little more involved.
Barefoot is truly a lifestyle which requires an educated barefoot trimmer (which can certainly be you, if you so choose), the right diet, movement, and the ability to be patient and flexible as your horse adjusts.
Depending on what you do with your horse, you may need to use hoof boots during the transition process. The key with barefoot is to be informed. Don’t just be a bystander, but instead an active participant in your horse’s hoof care!
