A boy and his dog.

That could be the theme of a fundraiser planned for Sunday called the First Annual Sean & Sophia Dog Expo & Social. It aims to raise money to pay the cost of raising and training Sophia to be a service dog for 7-year-old Sean Forsyth of Wexford, who has a high-functioning form of autism called Asperger's Syndrome.

Humans and dogs are welcome -- everyone must be up to date on their shots.

The noon-to-6 p.m. event at Misty Pines Dog Park will feature vendors, music, games, demonstrations, food, raffles and silent auctions. The dog park is located at 2523 Wexford Bayne Road in Sewickley.

Proceeds will benefit the Sean & Sophia Foundation.
