Her dog, with the formal name of Champion Pacific Icons Pint of Guiness, or simply Guiness for short, was named Best in Show at the conclusion of the show's first day.
Harrier dogs originate from England, where they were bred to hunt rabbits.
Guiness, who will turn 2 in August, is out to hunt championships.
"He's the number one Harrier in the United States," said Manning, of Stillwell, KS. "We love to come up to the South Dakota shows in Vermillion, Sioux Falls and Rapid City."
Manning is no stranger to Vermillion. She spent some time here attending The University of South Dakota before transferring to other schools for more advanced degrees.
She purchased Guiness as a pup. "He was one of a litter down in Texas," Manning said. "I studied those dogs for seven hours before I chose him."
Since then, it's been a dog's life for Guiness.
"He has a very mellow personality," she said. "He likes to take a sip of wine from your glass when you're not looking."
Manning's house is typically overrun with canines.
"I have six dogs at home, and they're all house dogs," she said. "That's what happens when your children all grow up."
She credits Guiness' success on Stan Flowers, his professional handler who knows how to make him look his best for the judges.
"And the judge for this show was Judy Webb, and she's very good," Manning said.
