Looks how to spot one

hair

The Vietnamese Pot-bellied Pig has a uniformly black coat of coarse hair. Its skin is heavily wrinkled, and the body is distinctive with a pronounced sway back and a large, sagging belly that may drag on the ground in pregnant sows. The head is small with an up-turned snout, small ears and eyes, and heavy sagging jowls. The feet are plantigrade, meaning weight is borne on all four toes of each foot, an adaptation to marshy terrain.1

Personality what they are like

Pot-bellied pigs are very clever and curious animals with a mind of their own. They communicate using at least 20 different sounds, including grunts, squeals, barks and screams. They are food-motivated and respond well to positive training, but can become demanding or vocal if bored or left alone for long periods. As prey animals, they dislike being lifted or restrained, which causes them extreme alarm. With regular gentle handling they become affectionate and enjoy learning tricks.234

Daily activity how busy a day looks

Pot-bellied pigs need daily outdoor time in a securely fenced yard for foraging, rooting and playing. They also benefit from leash walks twice a day, which provides bonding and exercise. Without enough activity they can become bored and destructive.23

Grooming and care the hands-on bits

Hooves need regular trimming. Their coat requires minimal grooming, but they should be checked for parasites. Veterinary care includes vaccinations and periodic faecal checks. In hot weather, provide shallow pools or shade because pigs lack sweat glands and overheat easily above 29°C.23

Home where they are happiest

Pot-bellied pigs can live indoors or outdoors, but in cold climates they must be kept primarily indoors because they cannot tolerate harsh winters. Indoors, use child-safety locks on cabinets and keep cleaning agents out of reach. Provide a litter box and soft bedding such as blankets or sleeping bags. Outdoors, a covered pen with shade and a shallow pool is essential. The optimum temperature range is 16-24°C with about 50% humidity.23

Food basics what goes in the bowl

Pot-bellied pigs are omnivores and need a balanced diet of commercial pig chow, supplemented with low-calorie treats such as fresh vegetables and fruit. Avoid high-sugar treats and chocolate, which may be toxic. Do not feed dog or cat food as it is too high in protein. Never restrict food to keep the pig small; proper feeding supports healthy growth.32

Company who they like around

Pot-bellied pigs are highly social and form strong bonds with their human family. They should not be left alone for long periods as they can become distressed and vocal. They thrive on daily interaction, training sessions and gentle handling. In some countries, keeping pigs as pets may be subject to local regulations; check your local laws before acquiring one.32

The story where it all began

The Vietnamese Pot-bellied Pig is a traditional landrace breed from the Red River Delta of Vietnam, particularly Nam Định province. Small numbers were exported to Canada and Sweden in the 1960s for zoos and laboratory use. From Canada, they entered the United States in the mid-1980s and were marketed as a novel pet, sparking a short-lived fad. Many of these early 'pot-bellied pigs' were crossbred and grew larger than expected, leading to some being abandoned. Today, properly bred individuals remain popular as intelligent companion animals, though the original Vietnamese breed is now endangered.145

Treats they will love homemade and simple

Banana Oat Piggy Cookies

These simple two-ingredient treats are low in sugar and high in fibre, making them a healthy reward for training or bonding. Oats provide slow-release energy, while bananas offer natural sweetness without added sugar.

You need

  • 2 large ripe bananas, mashed
  • 2 cups rolled oats (blended into a flour)

How

  1. Preheat your oven to 180°C (350°F).
  2. Blend the oats in a food processor until they become a fine flour.
  3. In a medium bowl, mash the bananas thoroughly.
  4. Slowly mix the oat flour into the mashed bananas until a stiff dough forms.
  5. Lightly grease a baking sheet or line with parchment paper.
  6. Drop spoonfuls of dough onto the sheet and flatten gently with the back of a wet spoon.
  7. Bake for 9–12 minutes until golden and firm.
  8. Cool completely before serving.

How much: Offer one or two cookies per day as a training reward. Always supervise your pig when giving treats.

Cheese Biscuit Training Treats

These four-ingredient biscuits are perfect bite-sized rewards for training sessions. Cheese provides protein and calcium, but the recipe uses only a small amount to keep calories in check.

You need

  • 1 cup shredded cheese (low-fat, e.g. mozzarella or cheddar)
  • 1 cup whole wheat flour
  • 1/3 cup milk (unsweetened, e.g. oat or cow's milk)
  • 1 tablespoon softened butter (unsalted)

How

  1. Preheat your oven to 150°C (300°F).
  2. In a bowl, mix the shredded cheese and flour together.
  3. Stir in the milk and softened butter until a stiff dough forms.
  4. Roll small balls of dough (about the size of a marble) and place on a baking sheet.
  5. Bake for 30 minutes until lightly golden and firm.
  6. Cool completely before offering to your pig.

How much: Use one or two biscuits per training session. Because these are richer, limit to occasional use.

Cranberry Orange Vitamin Punch Treats

These frozen treats provide a boost of vitamins and probiotics, making them a healthy and refreshing snack for mini pigs.

You need

  • 1/2 cup plain yogurt or Greek yogurt
  • 1/4 cup orange juice
  • About 12 fresh or frozen cranberries (dried cranberries may be substituted)

How

  1. Mix the yogurt and orange juice together in a small container.
  2. Pour or spoon the orange-yogurt mixture into each silicone pig mold or ice cube tray.
  3. When filled, gently drop one cranberry into each mold or cube.
  4. Place in the freezer and freeze until solid, about 1 hour.
  5. Store in the freezer and pop out one treat to feed immediately.

How much: Feed one treat per day as a healthy boost, not as a main meal.
