Where do Vietnamese Pot- bellied pigs come from?
You know, I'm not an expert on pigs but I'm guessing Vietnam?
Can Vietnamese Pot-bellied pigs be used for meat?
I wouldn't want to eat one. I've only seen them as pets and they are so cute! 
Are Vietnamese Pot bellied pigs inbred?
What an interesting question! I've never heard one way or the other. Have you ever owned one?
I have never owned one, but I hear their bellies drag on the ground.
Yes, ha! Do they have back problems? Seems like that would put pressure on their spines.
I have not heard anything about them having back problems from their bellies dragging on the ground.
I can imagine putting a leash on one and walking it around like a dog. I've seen people do that
