How to heal pigs in minecraft?

Me and my brother named a pug Tyra banks but he keeps hitting her on accident, we don't want her to die but how can we heal her?

You can feed pigs carrots

Splash potion of health, and feeding carrots

Like wolves, you can heal pigs with carrots, and splash potions of HEALTH. Be sure to check the potion's color and it's name before splashing it on anything. Keep your dog inside and make a pen for the pig OUTSIDE, so it can't escape, and so that something else won't attack it.
