Which of the following is a primary reason for cleaning tack regularly?

Regularly cleaning tack is essential primarily to avoid injuries to the horse. Properly maintained tack ensures that equipment such as saddles, bridles, and girths are free from dirt, grime, and sweat, which can lead to irritation or infection on the horse's skin. Clean tack fits well and is less likely to cause rubbing or chafing, which could result in painful sores or injuries.

While it is true that cleaning tack can contribute to its longevity, give a polished appearance, and help maintain its value, these factors are secondary in importance to the health and safety of the horse. The main goal should always be the welfare of the animal, as dirty or poorly maintained tack can compromise both comfort and performance.
