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.
Potbellies are herd animals with a strong pecking order.
If they are spoiled, they often become territorial, and aggressive towards humans, especially house guests. Porkers need time outdoors ,in a fenced yard, secure from hostile dogs. Pigs DO root, although this often can be somewhat curtailed. They do not get fleas, but DO get mange, which is easily treatable. It really depends upon the expectations and efforts of the owners.
