A small, slender, spotted ('painted') miniature pig prized as a highly intelligent and trainable companion. Despite 'mini' marketing, it is a true pig with substantial space, rooting, and zoning requirements.

Part of the Pigs
Domestic pigs — from intelligent 'mini pig' companions (potbellied, Juliana, Kunekune) to standard farm breeds. Smart, social, rooting omnivores that grow larger and live longer than buyers expect, need cooling and rooting space, and benefit from spay/neuter.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Minimum
Pen + wallow + shelter
50 sq ft per pig + wallow + 3-sided shelter + hog-rated fence
Pigs are intelligent social rooters — pair preferred over solo. Pen with wallow (for cooling — pigs can't sweat) and hog-rated fencing. Juliana is a small spotted miniature pet pig — still needs acreage, NOT a house pet long-term.

Recommended
Pasture + barn
1/8-1/4 ac per pig + wallow + barn
Rotational paddock for rooting, sturdy fencing, barn for farrowing.

Ideal
Managed pasture + woodland
1/4+ ac per pig + woodland + barn
Managed pasture rotation + woodland browse, mud wallow, shade, herd-mate, breeder/vet schedule. Juliana is a small spotted miniature pet pig — still needs acreage, NOT a house pet long-term.
Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Newborn
Newborn mammals are nursed on their mother's milk. Many are born helpless — blind, deaf, and sparsely furred (altricial, as in dogs, cats, and rodents) — while others stand and follow within hours (precocial, as in hoofed livestock).

Juvenile
After weaning, juveniles grow quickly and become increasingly active, playful, and independent. Adult coat, proportions, and (in many species) the permanent teeth come in as they approach full size.

Adult
Adults reach full body size and sexual maturity, with the species' mature coat and build. Sexual dimorphism — differences in size, mane, horns, or markings — is pronounced in some mammals and subtle in others.
Senior
Senior animals show aging signs such as graying fur, reduced activity, and a greater need for veterinary monitoring of joints, teeth, and organ function. Lifespan and the onset of old age vary widely by species and size.
Color & pattern variants
Natural variants occur in the wild; selectively bred (man-made) variants were developed in captivity.
Juliana pigs are not cage animals; they need a secure house-and-yard setup with both indoor space and a large outdoor area to root, graze, and wallow. Provide a draft-free indoor sleeping area with deep blankets (pigs love to burrow into bedding) kept around 65–75°F (18–24°C), and a securely fenced outdoor run with shade, a shallow mud wallow or water source for thermoregulation (pigs cannot sweat), and a designated rooting/digging zone such as a turned-soil bed or rooting box filled with substrate.
Fencing must be strong and low-escape (pigs are powerful, persistent diggers and lifters); hog panels or buried-base fencing work better than light wire. Flooring indoors should be non-slip, as splayed legs and joint injury are common on smooth tile. Because they can overheat easily, always provide shade, cool water, and a wallow in warm weather, and supplemental heat/insulated shelter in cold climates.
Substrate
Indoors, use washable rugs, interlocking foam mats, or sealed/laminate flooring over a soft yoga-mat layer to protect joints and prevent slipping; provide a deep straw- or fleece-filled bed in a quiet corner. Outdoors they need access to soil and a mud wallow for rooting and thermoregulation.
Equipment & setup
Juliana pigs are an indoor/outdoor companion pig needing secure fencing (hog panels), a draft-free insulated shelter, shade and a wallow for summer, and a deep heat-retaining straw bed for cold months; pigs cannot sweat, so a kiddie pool or misting is essential above ~24C. A snout-height rooting box, sturdy water bowl, and pig-safe ramps (no stairs for young/heavy pigs) round out the setup.
Diet
Feed a commercial mini-pig pellet formulated for potbellied/miniature pigs as the dietary base, measured to body condition rather than fed free-choice. Supplement with generous leafy greens and a controlled amount of vegetables; a small amount of fruit may be used as training treats. Provide grazing/rooting opportunities and constant access to fresh water.
Obesity is the single biggest diet-related welfare problem in pet pigs, leading to 'fat blindness' (fat folds occluding the eyes) and joint disease, so portions must be strict. Never feed dog or cat food, salty/sugary human snacks, or moldy produce, and avoid chocolate. Many pigs benefit from a small daily ration of hay or grass to satisfy chewing and gut motility. Consult an exotic/livestock vet on mineral and selenium needs for your region.
Behavior & temperament
Julianas are intensely social, curious, food-motivated, and roughly as trainable as a dog—they can learn to sit, target, walk on a harness, and use a litter or door. They form strong bonds, do best with a porcine companion or constant human family interaction, and become depressed or destructive when isolated and under-stimulated. Rooting is an innate, non-optional behavior; without an outlet they will tear up flooring, gardens, and furniture.
Provide daily enrichment: rooting boxes, treat-dispensing toys, snuffle mats, novel objects, and training sessions. Unneutered/unspayed pigs can become aggressive and territorial ('the teenage pig' phase), and learned food-aggression or 'door-charging' often stems from inconsistent boundaries, so calm, consistent, reward-based handling from the start is essential.
Health
Common problems include obesity and its sequelae (arthritis, fat blindness, hoof overgrowth, heat intolerance), overgrown hooves and tusks requiring routine trimming, dry/flaky skin and mange (sarcoptic mange is common and treatable), and dental disease. Pigs are prone to heat stress because they cannot sweat. Like all pigs they can carry and require monitoring for zoonotic and reportable diseases.
Prevention centers on strict weight management, routine hoof and tusk care, parasite control, dental checks, and an annual exam by a veterinarian experienced with swine—many small-animal vets will not see pigs, so line up appropriate care before acquiring one. Spaying/neutering is strongly advised for behavior and to prevent very high rates of uterine and mammary tumors in unspayed females. Always verify local zoning/ownership laws first, as many municipalities classify pigs as livestock and prohibit them.
Tips, DIY & hacks
Feed measured mini-pig pellets plus greens in a snuffle mat or scattered to satisfy rooting and prevent obesity, the biggest welfare killer in pet pigs. A DIY rooting box (tub of clean soil, hay, or large smooth river stones hiding pellets) channels destructive digging away from your yard, and pigs must be kept in pairs or with daily companionship as they are highly social.
