Without being condescending, your pig has you trained, just as it wanted. He squeals, you tend to him. He now knows when he wants attention, he just squeals and you will come running. You need to break this bad habit. When he squeals, do not say anything. Do not acknowledge him. What you are doing is rewarding bad behavior.
I will also be honest with you that a pig, pet or not, should be raised and kept outside, not in your house.
