Why is Surface Area Important to the Barefoot Horse?
Despite how we talk about heels and toes, a hoof is a singular digit which makes surface area and dorsal-palmar (front-to-back) balance extremely important.
While hoof-pastern axis or HPA is also something to be considered, a hyper focus on achieving a specific HPA or "aligning the bony column" can lead to imbalanced trimming. I am equally guilty of having made this error in judgment so it's important to note that I'm not shaming anyone. Let's normalize talking about and learning from each other's mistakes.
This horse was 6 weeks out from a trim and his heels, quarters and bars were much longer than his toes. This brings the heel further forward and drastically shortens the area that the horse is walking on.
The goal of a barefoot trim is to allow the horse to wear and grow relatively in balance. Of course that will vary case by case dependent on many factors including lifestyle, conformation and any lameness or restrictions higher up in the body. But if the growth rates are significantly imbalanced from the heel to the toe it is a good indicator that the trim hasn't been balanced.
Reduced surface area also interferes with the natural exfoliation of dead sole and can lead to retained and compacted material, further throwing off the trimmer's eye. I removed the excessive bar material which was causing debris entrapment and thrush problems, and was able to exfoliate some retained sole. More will be ready to let go by the next trim. He doesn't have a "low heel" despite removing the excess height and his HPA actually improved.
