Pot-bellied pig
The pot-bellied pig is a breed of domesticated pig originating in Vietnam.-Description:Considerably smaller than standard American or European farm pigs, most adult pot-bellied pigs are about the size of a medium- or large-breed dog, though their bodies are denser at 8 to 136 kg...

s that grow to be 150–200 lb (68–90.7 kg) were sent to zoos in Western nations in the 1960s. In the mid 1980's Keith Connell of the Bowmanville, Ontario zoo imported twenty breeders to Canada. Two of the pigs died in quarantine. The remaining 18 unrelated pigs were the foundation for the Potbellied Pig in North America. Because of the customs laws, only the offspring could be sold to the United States. US zoos were the main target for the piglets, but private owners soon began purchasing them as pets. Up to 5 additional imports were made in the following 10 years. To help track the pedigrees, the Potbellied Pig Registry Service, Inc (PPRSI) was created to preserve these bloodlines and establish a breed registry in the United States. These pigs average 150-200lbs. This registry was dissolved in the late 1990's.

The Miniature Potbellied Pig Registry Service, Inc (MPPRSI)was established in 1993 to provide a registry for those pigs who were pedigreed in the PPRSI and also met the breed standard of less than 15 inches tall. All of the foundation pigs were dually registered in PPRSI and MPPRSI.
In the UK, British micro pigs have been bred by Rob Rose in Cumbria since 1996.These pigs are a cross between KuneKune pigs (a NewZealand pig that weigh around 200lbs), Gloucester Old Spots (800lbs), and Tamworths (800lbs). After several generations of crossing the pigs have been marketed as truly tiny pigs that work well as pets. Unfortunately they have not been bred long enough to be considered a true breed and are not a consistent size or shape. After the initial press releases, breeders began popping up all over Britain trying to push pocket-pigletts wich later became genuine hogs unfit for suburban dwelling. This is one owner's tale of her 2ft tall "teacup pig" from the "Little Pig Farm" owned by Jane Croft. Jane Croft is no longer breeding pigs and has filed for bankrupcy. British micro pigs are not only found in zoos, animal parks and open farms, but are also kept as pets.
In this days people also use the names mini, pixie, dandie, micro, thimble and pintsize, as well as teacup.
Unfortunately there are breeders who are selling "miniature" pigs that are simply immature. Newborn piglets can be as small as 4oz and easily fit in a teacup, but will not stay tiny. Because potbellied pigs don't reach their mature size until they are three years old but can breed as early as three months, some unscrupulous breeders are selling newborn piglets born to immature parents and claiming the babies will stay small. It is important for any potential owner to check out the parents and adult siblings and only choose reputable breeders who have years of experience.

As pets

Miniature pigs, also known as micro pigs, have seen an increase in popularity. They can be house-trained, and keep themselves exceptionally clean, despite people believing that pigs are dirty creatures. Micro pigs are unfortunately being abandoned, as many people do not know how to properly care for them. .
