What breed of pig as a pet?
I would recommend a pot bellied/Miniature pot bellied or a penny-well.I have two penny-wells and they are house trained,they go outside in the day though.You cn treat penny-wells and pot bellied pigs like a dog,i put rainbow and misty on a leash and take them on the park.They have to have a diet including:fruit and vegetables(peelings or whole,i have a compost heap with peelings)pig pellets,hay or haylage(haylage is only for pigs born with dust allergies or hay fever)Those are a few of the very important things in their diet.
