The relationship of frog pressure to heel expansion.
A study was carried out on five horses and four ponies to assess the effect of altering frog pressure on hoof expansion. Measurements of hoof expansion were made using strain gauges. It was concluded that whereas frog pressure affects hoof expansion, it is only one of several factors. Increasing frog pressure may result in increased expansion, or contraction, or may have virtually no affect. The variable results of changing frog pressure should be taken into account when considering therapeutic shoeing.
