Dogs are invited to bring their families to trick-or-treat and celebrate the holiday at Sherwood Dog Park in Paso Robles. Costumes are encouraged but optional.

The pet costume contest is free and open to children and adults of all ages and their pets. The costume contest will be held at 11 am with prizes for the winners.

Free hot cider, coffee, and refreshments will be served. Holiday family photos will be available for a $10 donation.

Proceeds benefit Sherwood Dog Park, a non-profit organization. Rain cancels.
