Big soft bed. Your pig will love you to death when you bring this home for him.  I found one at a pet store (no brand or label was on it.)  Find something that you can throw in a washing machine (because you will need to often.)  The bed Dixie has is really a big oval shaped pillow with a removable casing.  The bottom of the casing is made of canvas and the top is a very soft cottony fabric.  The casing has a zipper so you can remove the pillow.  I have to put the pillow in an extra-large washer for cleaning.

Sheets and/or blankets. To cover the pig while she sleeps.

Food bowls. It really doesn't matter what you use.  I have heard many people say that pigs constantly need access to water so they won't get thirsty.  If you give your pig constant access to water, all the pig will do is overturn the water and try to wallow in it.  Give your pig all the water he wants while he is eating and make sure your pig always has water while they are outside, especially on a hot day.  I found this nifty little water and food bowl set that allows you to fill up a 2 liter bottle with water, turn it upside down and literally screw it into the set.  Your pig has lots of water, and you don't have to keep getting up to make sure he hasn't run out.  I do not give Dixie more than the 2 liter bottle of water while she is eating.

Small plastic child's pool or sandbox.   See "Outside Play Time" for more info.

Scrub brush.  Get the kind you could use to scrub the tub basin.  This will serve two purposes:  you can brush/scratch your pig with it and you can use it to scrub your pig while giving her a bath.  Dixie loves being brushed vigorously with her brush.

Shampoo.  For washing your pig.  You can get the smelly kind, and then start calling your porker "Fruity Pig."  :)

Harness and leash.  For taking your pig outside.  For more info, see "Being Creative For Your Pig."

Litter box.  Or you can train your pig to go outside.  But I would still recommend training your pig to use a litter box.  The pig may drink more water than normal one day and may have to potty when you aren't around to take him out.  For more information, see "Being Creative For Your Pig."

A space just for your pig. I am talking about a sleeping area.  If your pig is kept outside, you really don't have to worry about this because the outdoors is your pig's space.  Dixie likes having a space that she knows is hers and noone else's.  When I first got Dixie, I lived in a small apartment, so Dixie's space was the kitchen.  I moved to a place that has a room just big enough for a washer and dryer.  Since I have neither, this has become Dixie's room.  She seems to like it better than the kitchen at the old place.  She does prefer to hang around whomever is in the living room, but I have seen her just get up, walk to her room, and fall asleep there.

Carpet Freshener.  If you have an inside pig, you need to use this to keep your house from completely smelling like pig.

Carpet Cleaner.  If your pig has his own "room," chances are he has soiled its floor several times.  No matter how many times you try to vaccuum the floor (if it's carpet) or mop the floor (if it's linoleum), you just can't get that pig waste smell completely out.  Use a liquid spray designed to get pet smells out of flooring.  I just invested in some and am amazed at the results.

Toys.  See "Inside Play Time" for more info.

Fence or tie-out.  So your pig can stay outside for long periods of time without your having to be with him.  See "Outside Play Time" for more info.

Skin lotion.  Pigs have very dry skin.  You can rub your pig all over with some lotion.  Your pig will be moisturized AND happy you're giving him attention.  Your pig will think he's in heaven.

Bug spray.  To ward off evil insects while your pig is frolicking outside.
