In 1986, when the first potbellies were sold into the U.S., their market price ran well into the thousands of dollars. Recently, as the breeder market became satisfied, the price of pets has come down to match that of pedigreed dogs and cats, making them an affordable alternative to canine and feline pets. These pigs came to the United States from Canada. . Full grown potbellied pigs weigh an average of 70-150 lb. with some reaching 200 lb. or more; they average 3-ft. long and 15-inches tall. Full growth is not reached until about 5 years of age. Colors range from solid black to solid white, with a var iety of spots in between. People ask, "Which make better pets, males or females?" We have found that as long as either sex is neutered or spayed, it really doesn't matter.
