The truth about pigs is that their reputation for being dull and dirty is undeserved. The pig is actually a curious and intelligent animal. For instance, a pig will not take anything for granted; it will poke, and prod something until it arrives at a conclusion. A pig’s intelligence is so keen that the animal needs to do something only once – such as turn on an automatic drinking fountain – to know how to do it again. Furthermore, pigs are basically no dirtier than any other farm animal. Because pigs don’t sweat, they seek out water in order to cool off. On a farm, the water that a pig finds is usually in a mud puddle. However, the pig would be just as happy splashing in a bathtub since it is water, not dirt that pigs enjoy.​
