Treats for pigs run from small training rewards for mini pigs to larger bagged treats for farm pigs. A mini pig takes treats as part of the day, and small pieces that are easy to count keep that simple. Judge a listing by its main ingredient, by the size of each piece and by how the pack is sold. A treat that breaks easily is simpler to portion than one that has to be cut. Smaller animals have their own shelf in small pet treats.
