Talented dog walks itself

Chicago - Sporty isn't like most dogs.

He's a fixture on Chicago's River Walk and he stands out because Sporty can walk himself, holding his leash.

David Duncan adopted Sporty. a former agility and championship show dog.

Sporty is still a star today, bringing joy to Chicago pedestrians.

"He was in Chicaco Magazine. He was in New York Mag," said Duncan. "He's everything. I don't know what I'd do without him, I really don't."
