We have two of these micro pigs. I recommend getting a female. Thy we're so cute as babies, and only about the size of a soda bottle.
The male is a territorial jerk. He is very protective of his horses, and appears to monitor the herd. If they are separated into different fields or if a mare is brought in,, he goes through the fence or under the gate to check on every one of them. He is not tamed in any way, though he is not afraid of us. He hangs in the barn, comes up for his breakfast, and keeps a watchful eye on everything. Occasionally we have to run him out of the barn if he starts popping his mouth at us, but he hasn't done anything beyond that as far as aggression. He is UGLY as sin too. He is lean and scruffy and muscular from running in the field all day. He sings little songs as he is doing his mare checks. It is cute.
The female is a real sweetheart. She doesn't really tolerate handling unless you have treats. If you have treats, she will sit and lay down and let you pet her, and I think mom might have taught her some othe tricks. She is typical fat piggy. She does not get a whole lot of food a day. She shares a tiny bit of grain with the male for breakfast, and just spends her day rooting in the fields at a slow walk, or sleeping in the hay. She is a lazy thing and chooses not to get the kind of exercise the male does. She is last from all of her rooting. She can pack up and run if startled, but prefers a slow waddle. She is a very pretty piggy.
