If you want a well mannered pig I recommend doing tricks. Pigs love to learn new tricks especially for a treat reward. This hoop is heavy duty! It's actually a sports hula hoop that snaps together. This is not the thin cheap kids hoop. This is 1 1/2" thick and quite large with a diameter of 33". Your pig will never get to big for this ring. I actually do not use all the pieces of the ring I remove one if not I feel it's too big. I will include all 8 pieces but I recommend using 7 it will still be a perfect circle. This heavy duty ring sells for $40 on other sites.
