Where are a rabbit's sweat glands primarily located?

Rabbits have very few sweat glands compared to other animals, which means they do not rely on sweating to regulate their body temperature. The primary location of sweat glands in rabbits is indeed on the underside of their front paws. This unique adaptation limits their ability to cool down through perspiration, making them more susceptible to heat stress. Instead of sweating, rabbits primarily regulate their body temperature through behaviors such as seeking shade or resting on cool surfaces.

The other choices do not accurately represent the distribution of sweat glands in rabbits. Although rabbits have other methods to manage their temperature, the limited presence of sweat glands focuses the rabbits' cooling mechanisms primarily on their paws.
