Stump came out of retirement last week to compete.
His handler and other co-owner, Scott Sommer of Texas, competed with six other dogs for the title.
Stump won Best in Show last night at the Westminster Kennel Club dog show in New York.
Take a look at some photos taken at the competition.
At the age of 10, that's about 70 in human years. He's the oldest Best in Show winner.
With floppy ears and a plodding gait, the golden-red Stump was an instant fan favorite at the Garden.
A nearly full crowd cheered loudly when Stump was chosen from a field of seven that included a giant schnauzer that was the nation's top show dog, a favored Brussels griffon, a Scottish deerhound named Tiger Woods, a standard poodle with 94 best in show wins, a Scottish terrier and a puli.
