Chances are you don't, especially if you can wring out your shirt at the end of a hot day. Their mucky appearance gives pigs an undeserved reputation for slovenliness.

Pigs are smarter than any other domestic animal. Their ability to solve problems, like the pig I.Q. test on THE JOY OF PIGS, is well-documented, and they are considered by animal experts to be more trainable than dogs or cats. Pigs are difficult to classify. To pig farmers, the animal is a commodity. To truffle harvesters, pigs are reliable hunters whose keen sense of smell locates these pricey fungi.
