The good news is that pigs are very trainable. First, a pig must be taught that it can trust its owner. Firm, gentle discipline works well. Because of their love for food, positive reinforcement is effective. Negative physical reinforcement is not.
Pigs have a great memory, and respond well to commands.
Pigs are capable of learning to slam dunk a basketball, play a piano, or golf, play soccer, jump through hoops, dance, ride a skateboard, or skooter, and dozens of other feats. Housebreaking comes very easy to pigs. What few knew, was that the pig grows, beyond the age of one year, and often is too large to ride in a car to go to the vets. This problem can be overcome, if the owner is dedicated, by training a pig to climb a ramp into the car. All pigs must be neutered to be good pets.
