You need to walk your dog, so why not walk with everyone else in your community at the same time? A pup walk can be as simple as selling a ticket, providing a goodie bag, and arranging a meetup location, or as elaborate as closing down the streets, adding in contests, and making a parade and festival out of it. Go wild!
Guided Tours / Open House
Collaborate with a local landmark or venue that isn’t normally open to the public and arrange a day for guided tours. Sell tickets in advance. Also offer concessions.
