Every dog has his (or her) day and today is that day out at Holden Arboretum. At the annual Woofstock event, dog owners can bring their pets and take them on a one-mile dog walk. Other canine-related events include a pet agility test and shopping on "Vender's Rrrow." The event takes place today from 9 a.m. until 3 p.m. and admission is $5 per car. (Niesel)
