Which of the following is NOT a benefit of shoeing a horse?

The correct answer highlights that improved circulation in the hooves is not a benefit of shoeing a horse. While horseshoes do provide various advantages, such as enhanced traction on hard surfaces, protection from wear and injury, and support for abnormal hoof conditions, they do not inherently improve circulation.

The hoof structure includes mechanisms, such as the frog and the digital cushion, that contribute to circulation within the hoof when the horse is moving naturally. When shoes are affixed to the hoof, they can restrict some of these natural movements, potentially leading to reduced circulation rather than improvements. This is why it's essential to balance the benefits of shoeing with maintaining proper hoof health and functionality.
