Jerry "Bud" Mitchell and wife Bonnie tells the Daily Corinthian that the horse was killed Sunday night in a barn.
Bud Mitchell said he found the dead horse with a pit bull still in the stall. He said the dog was gone when he returned with a gun. He said he found a second pit bull dead in the barn
Bonnie Mitchell said two four-month old stud colts were being kept in the barn after being weaned from their mothers. The other horse in the stall wasn't harmed.
Bonnie Mitchell said evidently the "pony kicked hard enough to kill one of the pit bulls."
"My concern is for the one (dog) still loose," she said. "I'm afraid to go in the backyard now."
The Mitchells have been raising miniature ponies for six years. The barn where the attack took place is 110 feet from the couple's home.
Mitchell said the pit bull that escaped was brown and had a white face.
"I want the public to be aware there is a dog that killed and is now on the loose," said Mitchell. "It could be a child next time . you never know what those kind of dogs will do."
The Alcorn County Sheriff's Department is investigating the incident.
