@bikejourno in 2007 my wife got a young and small Vietnamese pig since it was the year of the pig. We had her for about 3 or 4 years until she got to be about the size of the one in your pictures. We then gave her to a guest farm in Ilan where she is now the elderly animal at the farm. She liked to take walks with us but she didn't like a leash. She was just like a young dog in that she would run ahead of us by 20 or 30 meters examine something and then wait for us to catch up to her. Other times she would stop to examine something and then jog to catch up to us. She was a very good house pet except she didn't need much if any affection except she did like to be scratched.
