The common practice of trimming heels short in order to achieve an idea of "ideal" (healthy ground contact for the frog) contributes to unhealthy compensatory posture which causes tissue to eventually breakdown and results in a plethora of problems for horses (and their owners).
Yes, in a healthy hoof, the frog WILL come into ground contact, however, trimming a hoof to achieve this when it isn't appropriate and where it will inadvertently create more issues is totally avoidable.
Unhealthy posture is also mostly unavoidable and in today's post, we're literally scratching the surface on the topic of ideal hoof morphology and posture and why frogs, heels and posture might be connected...
A fully functioning hoof will be attached to a limb which will be perpendicular to the ground in the relaxed, healthy horse, when standing on a level surface. Anything other than ideal posture requires further investigation as to why the horses proprioception sensors are telling the horse to make other choices, despite this creating problems immediately and further down the line.
There are many reasons for unhealthy posture and the hoof is a major influencer. It both contributes to unhealthy posture and also suffers as a result of unhealthy posture, and it isn't always clear what comes first. If posture improves because of a change in hoof care, then this is both powerful informative and empowering for the horse owner!
We document posture and hooves as part of our diligent documentation and investigations at every consult. We are not the only hoof experts to do so - leading farriers, trimmers ad podiatrists take note of postural changes and are aware of the influence hoof care can have as a way to positively intervene and also as a route to create unhealthy ideals.
Below we feature an aged Shetland pony who had his first proper trim with Beccy and doesn't have ideal hoof morphology but we are able to positively influence the breakover, torque and dorsal/palmar angles to positively influence his posture and gait! If (like common barefoot and farriery trends), we were to lower the heels on these particular hooves so that the frog is in ground contact we would create:
