Quince the Australian shepherd fled from his handlers' home in Harrison City around 11 p.m. Wednesday.
Handler Jeffrey Hanlin says the 6-year-old dog leaped over a backyard fence during a fireworks display.
Hanlin tells WTAE-TV Quince is owned by Cincinnati Reds catcher Ryan Hanigan and his wife. Quince was supposed to compete in a show in West Virginia this weekend.
There's a $1,500 reward for Quince's return. Hanlin says Quince is very approachable and can be coaxed by someone using a "happy voice."
