What are the digits that do not bear weight called?

The digits that do not bear weight are called dewclaws. Dewclaws are typically found on the inner side of the leg in certain animals, such as dogs and some livestock, and they serve various functions depending on the species. They do not make contact with the ground during typical movement, which is why they are characterized as non-weight-bearing digits.

In many species, dewclaws can play a role in stability and grip, especially when navigating uneven terrain. They are remnants of evolutionary adaptations and can be seen as a vestigial structure in some animals, having lost their primary function of weight support.

Understanding dewclaws and their role in anatomy can help clarify the distinctions between different types of digits, such as hooves or claws, which do directly support the weight of the animal during movement.
