Whimzees are a great chew treat for pigs. I find the best prices on Amazon.
Oinkbox has a great food, dental stix and treats. They are a fantastic company and I love supporting them.
Bedding
Bed - I don't spend a lot of money on pig beds. Some piglets tend to pee on their beds. I like to go to places like TJMaxx or Marc's and find beds cheap. That way when I have to wash them and they fall apart, its not a big deal. I wait until a pig has matured a bit before I spend more on it's bed. Pigs love beds that they can cuddle up in like the ones below. I buy these or these on Amazon.
Blankets - I don't spend a lot of money on blankets either. I like to get blankets at Good Will.
Heating pad - I buy my heating pads at Target and Chewy.com. They are nothing special.
POTTY
I use a rabbit pan for litter boxes. I buy the at Tractor Supply or Amazon.
I like to use washable pee pads in the litter boxes. I buy them from Amazon.
Any baby shampoo or soap works just fine. I use an animal shampoo from Young Living.
Towel. I use a pet towel from Norwex but any towel will work.
Treats in the tub - peanutbutter, Cheerios and fruit. I love to use a LickiMat.
Other supplies
Harness/Leash - I buy mine from Pig Gear. She has a website and Etsy shop. Use my discount code on her website. (autumn)
Hoof Trimmer - a Dremel works great (60-80 grit) if you can desensitize your pig to the sound and vibration. Or you could use a technique where you flip your pig upside down. There are many YouTube videos explaining how to do it. I use horse hoof clippers.
Toys - Pigs won't just play with any toy. Most won't play with any toy that is not a treat dispensing toy. I get our treat dispensing toys from Oinkbox. A lot of pigs also enjoy toys that have a crinkle noise.
Gate/Enclosure - Pigs are very strong. There are few baby gates and enclosures that can hold a pig during its entire life course. But while a piglet is young, any metal enclosure that is held securely in place will work fine. Another option is a secure area built of wood. Just make sure it is at lease three feet high so your pig doesn't jump over it.
