Danny Stewart and his wife, Deedee, were feeding their horses when they heard a dog barking in their pastoral area. “We couldn’t find this dog barking until we came upon it,” Danny said. There, at the base of a septic tank last week, they found a 50-pound, black mixed-breed dog. Not thinking the septic tank was too deep, he jumped approximately eight feet down into the tank. “I busted my butt,” he said.
