Do not get a pig from a large pet store that has a chain of other stores( and most of the non-chain pet stores, but I have gotten one from a family friend's pet store before, and they definitely know ALOT about the piggies). I bought my current pig, Cocoa, from a pet store, they guaranteed me 'she' was a female, and when I brought a guinea friend home a week later, Cocoa showed some VERY un-girl like behavior. We took him to another pet store(our family friend's) and they told us that he was definitely a boy. Well, I could not get rid of him now, I was way too attached, and I am so happy I didn't, he's the sweetest little boy in the world, but just goes to show you, Petsmart and Petco know NOTHING about small animals.
