If a shoe is excessively thin, what action should be taken?

When a shoe is excessively thin, the best course of action is to remove the shoe and rest the pony. An excessively thin shoe can compromise the hoof's protection and integrity, increasing the risk of injury to the hoof wall and sole. Over time, this condition may lead to pain, discomfort, or even more serious problems like abscesses or lameness. Removing the shoe allows the hoof to recover and regain strength, while also preventing any further damage during that period.

Resting the pony helps in allowing natural hoof growth to occur without the added stress of a compromised shoe, ultimately promoting better hoof health in the long run. Other options, such as applying hoof oil or redesigning the shoe shape, do not address the immediate concern of the thin shoe and may not provide adequate protection or recovery for the pony. Thus, focusing on resting and properly caring for the hoof is crucial.
