The phrase "sweating like a pig" may evoke mental images of streams of sweat pouring down the pigs' skin on a sweltering-hot day, but it is one of the English language's highly misleading idioms. Pigs have only a limited number of functioning sweat glands so they only sweat a small amount, and what little sweat they do produce doesn’t much affect their body temperature. So how do pigs cool themselves down? Like this happy darling at Melief - animal sanctuary, pigs enjoy wallowing in water or mud
