In my experience pigs are easier to train than dogs (they learn more quickly) and are less easily distracted. I trained pigs for 4-H and showed them at the county fair. I could walk a pig around with just a cane to tap it and keep it going the way I wanted. Bringing my dog to the fair would likely take all of my strength trying to hold the leash. Dogs require acclimation to novel stimulating situations or they forget their training. Pigs don't seem to care.

The interesting thing to me was that if we forgot to feed them they would always seem to be able to take apart the fence and get out to eat. The patriarch got out and visited the other pens before he passed away which reinforced my feeling that they treated each other like family.

Read the first google hit for pig intelligence if I haven't already gone on too long on the subject.
