Both of those pigs are adorable! Traveling Gypsy, I do think pigs should be in a group of at least two. I think the reason QtrHorse's Louee is doing so well, is because he can have run of the place, and has lots of interaction with humans as well as other animals. Is your pig just penned up by himself all the time? If so, he probably is lonely and bored. I would consider finding him another home, ONLY if it would be a better situation for him---that means being able to actually go and see where he will be living. If people interested in him don't agree to thios, then they aren't the right ones to have him. Good luck---maybe if you can just spend a couple of hours a day playing with your pig, you won't have to find him a new home at all.
Everything can be achieved through patience!
I'd rather have a problem horse than a problem man. The horse I can work with. The man---I cannot help!
