No. Pigs do have sweat glands but they do not function like a human's does. They can release a little water and heat through passive diffusion, but it is not enough for the pigs to rely on. So in order to combat heat, pigs have adapted by using behavioral thermoregulation, which is the act of cooling themselves in the mud or water.
Pigs sweat but not the way humans do. Pigs do not have eccrine sweat glands which are used for temperature regulation in humans through watery evaporative coolness. Pigs have apocrine glands which excrete protein, ammonia, lipids, and chromogranins and the bacterial decomposition of these leads to odor so perhaps that's where the origin of the idiom lies since it a generally accepted concept that sweating leads to odor.
Mice do not have sweat glands, so no they do not sweat. They cool off by dilating the blood vessels in their tail and ears and slow metabolism.
Pigs actually don't sweat blood, they have glands that produce a red-colored secretion that acts as a sunscreen and inhibits bacterial growth on the skin. This secretion is often mistaken for blood, giving rise to the misconception that pigs sweat blood.
The phrase "sweating like a pig" is a misnomer because pigs do not have sweat glands like humans. They lack the physiological mechanism to regulate body temperature through sweating, so they often use wallowing in mud to cool down. Thus, the phrase is inaccurate in describing excessive human sweating.
There are animals who do not have sweat glands. Animals like reptiles and fish don't have sweat glands. Pigs and elephants lack them too.

Aside from humans, several others animals are able to sweat. These animals include horses and other primates like apes and monkeys.
There are 250,000 sweat glands in a pair of feet.

No, they have sweat glands
There are approximately 20-30 sweat glands in a person's armpit.
Because they don't need them, because mud and water are available to them year round.
Only mammals have sweat glands. Dinosaurs were reptiles, so they did not have sweat glands.
Pot belly pigs are the only mammals that do not have sweat glands. They use mud and water to cool themselves off.
