Off the Leash Sponsorship Opportunity. You can contact firstname.lastname@example.org for a form to order your sign today. So how does it work? A $200.00 contribution receives an 18” X 24” sign to be placed on the fence in the Dog Park. Additionally, All Dog Park Sponsors receive recognition on our social media site as well as our web site. The sign will remain in place for one year. Renewal of existing is $100.00 annually.
