At the end of High St in Burlington City is the Riverfront Promenade and alot of people walk their dogs there. Have you been there? Also Laurel Acres in Mt. Laurel has a dog park and in Medford is Medford's Freedom Park on Union St. off of Jones Rd. which is a really nice dog park where you can let them off leash. There's Smithville Park in Easthampton and Burlington County College Sculpture Garden in Pemberton Township. Hope this helps!
