Now that Scout is house trained, I'm more comfortable with him. House training is a human expectation not necessarily shared by canines. A clean house matters to me, but, without training, my dogs wouldn't care where they peed and pooped.
That's not true of pot-belly pigs.
As a volunteer at the Oakland Zoo, I fed the pot-belly pigs, fluffed their blankets and pillows, and swept the dust out of their indoor living quarters. Those pigs never messed indoors, not once in the three years that I observed them. And furthermore, pigs don't need house training--sanitation comes natural to them. In fact, pigs purposely establish designated areas outdoors to do their business, well away from their shelter, bed, and food.
Given an appropriate living space, contrary to the popular saying, "Dirty as a pig sty," pigs are the cleanest mammals on the face of the earth.
