I use to live on a farm on my land on the reservation and we had alot of animals from pigs, goats, rabbits, chickens, geese, roosters, ducks, horses, a lamb and these baby emu's ( I think thats how you spell it) but the best kind of pig to get for a house pet is a potbelly or a royal dandie. I use to have one named Sissy. I got her when she was really tiny, I had to bottle feed her which is what you should do is get one small enough to bottle feed ( I even bottle fed the kids which are baby goats and my lamb Georgey ). Id prefer a runt because some people kill them anyway but when their that tiny their alot easier to train and treat just like a baby and get em use to your other pets. They do eat dog food, never feed them slop (table leftovers) because thats just getting them to be like an outside pig and you can show em tricks just like a dog. Its pretty much like raising a dog or a little kid and they do have to get shots, etc. Dont ever intoduce them to mud though, another bad outside habit. You can bathe em and dress them up. But Id read more on it.
