I see you live in Georgia. It's important to keep her cool.
Is she an inside or outside pig? If outside make sure she has plenty of shade and they love water. Some people use the little hard plastic kiddie pools to keep them cool. Those work pretty good as long as the sides are low enough for her to step into. Plus you will need to dump it out pretty often because they potty while they are in the water.
Get her used to having her feet handled. She will need to have her hooves trimmed. And that can be a real nightmare when she is full grown if she isn't used to it.
Feed her a pelleted pot bellied pig food, and lots of veggies. Some fruits are ok. Try to stay away from bread and stuff like that because they can get overweight easily. Fresh hay is good for them too.
Pigs root, it's a natural thing for them to do. If she is a house pig, give her a low box and put some interesting things in it for her to root through.
If she is outside keep her away from your flower beds, but give her an area where she can root.
There are lots of pot bellied pig sites, and rescue sites, online. Even some Yahoo groups.
I have 3 pots and enjoy having them here. They each have their own personalities.
