Potbellied pigs are clever, distinctive animals that can learn routines and even be house-trained. But “mini pig” is not a promise of a tiny adult: size varies, pigs root by nature, and suitable housing, diet, veterinary care, and local permission all need planning.

What do potbellied pigs look like?

1. Their silhouette is distinctive

Potbellied pigs typically have a short to medium wrinkled snout, small upright ears, prominent jowls, a short neck, a rounded belly, a swayed back, and a straight tail ending in a switch. Merck Veterinary Manual describes these traits in its September 2024 update.

2. Black is common, but not the only coat color

Many are black, sometimes with white markings; gray and completely white pigs also occur, according to the Merck Veterinary Manual.

How big do potbellied pigs get?

3. “Mini” does not mean a guaranteed small adult

Merck says adult potbellied pigs should not exceed 18 inches at the shoulder, but miniature pigs as a broader group vary. The label “mini pig” does not guarantee a particular adult size.

4. Adult weight varies considerably

Even trim mature potbellied pigs can weigh well over 100 pounds, depending on breed; most mature potbellied pigs average under 200 pounds, Merck reports. Those figures describe a variable population, not a target weight for an individual pig.

5. Growth can continue for years

VCA Animal Hospitals says mini-pigs generally reach about half their adult size and weight by one year, then continue growing until around four or five years. That is a general statement about mini-pigs, not a precise growth schedule for every potbellied pig.

How long do potbellied pigs live?

6. They can be a long-term commitment

Merck gives a possible lifespan of 8–25 years and says 10–15 years is common in healthy pigs. VCA gives a different range, so lifespan estimates vary and should not be treated as a guarantee. A pig may remain part of a household for many years.

What are potbellied pigs like to live with?

7. They are intelligent and can learn house-training

Texas A&M College of Veterinary Medicine & Biomedical Sciences describes potbellied pigs as very intelligent and says they can be housebroken. Training ability does not make them low-maintenance: their daily needs and natural behaviors still have to fit the home.

8. Rooting is normal behavior

Pigs root with their snouts. Merck advises providing an appropriate rooting area; without one, a pig may disturb soil or household materials while following that instinct. Plan for enrichment and for some disruption rather than expecting rooting to disappear.

9. They are not a good fit for every home

Merck says potbellied pigs are unsuitable for apartment dwellers and high-density condominium complexes. Their space and rooting needs help explain why. Consider whether your home and outdoor access can accommodate those needs before bringing one home.

What do potbellied pigs eat?

10. Their diet needs to be species-appropriate

Texas A&M recommends commercially available potbellied pig feed because pigs have specific nutritional needs. Its 2011 article warns that human food and overfeeding can contribute to obesity and later health problems. Ask a veterinarian familiar with pigs to advise on an individual animal’s diet and portions; neither a general feed category nor an individual source’s recommendation replaces that guidance.

What housing and daily care do they need?

11. Outdoor housing needs room

For an outdoor setup, Merck recommends at least 50 square feet per pig. This is the manual’s guidance, not a universal legal standard. The same guidance describes an outdoor pen with a structure such as a large dog house for sleeping, feeding, and watering.

12. A secure fence is a safety measure

Texas A&M warns that pigs have no defense against dog attacks and says a fenced area helps protect them. Include secure boundaries in your housing plan.

13. They are vulnerable to heat and cold

Merck gives adults a comfort range of 65°F–75°F (18°C–24°C). Temperatures above 85°F (29.5°C) are stressful because pigs do not sweat. Housing should let the pig stay within a suitable environment rather than relying on the animal to cope with extremes.

14. Outdoor pens need regular cleaning

In its outdoor-housing guidance, Merck calls for removing feces daily and adding fresh dirt to cover and absorb urine. A clean environment is part of the care routine, not an occasional extra.

What health care should owners plan for?

15. Hoof maintenance is routine care

Merck identifies routine hoof maintenance as a special care need, and Texas A&M includes hoof trimmings in its annual-care guidance. Ask a pig-experienced veterinarian how often an individual animal needs attention.

16. Dental care deserves attention too

Merck also calls for special dental care. The specific needs can depend on the pig, so discuss dental checks and care with a veterinarian rather than assuming routine dog or cat recommendations apply.

17. Veterinary care takes advance planning

Texas A&M’s 2011 article recommends annual vaccinations, hoof trimming, and physical examinations. Its advice is a useful prompt to plan ahead, but current care decisions should be made with a local veterinarian experienced with pigs. Before acquiring one, identify where you can get routine and urgent care.

Can you keep a potbellied pig in a house or apartment?

18. House-training does not settle the housing question

A pig’s ability to learn house-training is only one part of suitability. Merck advises against keeping potbellied pigs in apartments and high-density condominium complexes, and its care guidance describes space, rooting opportunities, and outdoor housing needs. Evaluate the actual setup—not just whether a pig can be trained to use a designated area.

19. Local rules can decide whether you may keep one

Merck says many ordinances classify potbellied pigs as livestock and advises checking local rules. Regulations differ by location, so confirm the rules with the relevant local authority before acquiring a pig; do not assume a pig is permitted because a neighbor keeps one.

Is a potbellied pig right for you?

Before deciding, check that you can provide suitable space and rooting opportunities, secure outdoor boundaries where needed, an appropriate diet, regular hoof and dental attention, and access to pig-experienced veterinary care. Also consider whether your household can accommodate an animal whose adult size varies and whose lifespan may span many years. Texas A&M’s 2011 article quotes veterinary faculty member Dr. Kevin Washburn: “A good candidate for owning a pot-bellied pig, as with any pet, is someone who has time to devote to caring for the animal and who is prepared financially to provide veterinary care, should it become ill or have other problems.”
