Most teacup or micropigs pigs grow to weigh between 40 and 200 pounds. Many breeders claim teacup pigs only grow to be around 35 pounds, but a pig weighing only this much is usually underfed and unhealthy.
Unscrupulous breeders sell teacups to unsuspecting owners, claiming the animal will always be small. Buyers should be wary and understand that any pig weighing under 40 pounds is probably underfed and unhealthy. There are plenty of pig breeds that grow smaller than their cousins but will not remain small and cute for long.
Breeds of miniature pigs include the Juliana, Vietnamese potbellied pigs, Yucatan and Sinclair. There are more than 50 types of miniature pigs and finding these or other breeds when shopping for a teacup pig is usually easy.
Breeders consistently try to create a line of pigs that stay small, some under 12 pounds. Buyers should know that this never works, and even small breeds can grow very quickly. It takes between four and five years for a pig to stop growing. Many pigs are turned over to rescues or animal shelters because their owners didn't realize how big they would get.
There are many pigs available for adoption in every state in the country. Before buying a pig, an owner should look into adoption to help save a life and find the perfect pet, but be careful. Many cities around the U.S. and in other countries don't allow pigs as pets, even small ones. Prospective owners should check their local laws before adopting or buying a pig.
