If Fido prefers off-leash locations of the sandy variety, look no further than Sullivan’s Island. With varying seasonal hours, Sullivan’s lets local pups cruise the shoreline without that pesky leash. While there are some rules — dogs need a Sullivan’s dog permit available through the town — this beach still reigns supreme as Charleston’s most dog-friendly location. Head out to the beach on a warm spring day, and you’ll be bombarded with the kind of cuteness any dog lover would pay good money for. You also know that your dog is safe, because all of his new friends are town-approved, with up-to-date vaccines and all that other good stuff that keeps your pup healthy. We can offer one tip for these weekend trips: bring an extra ball or three. The ocean is a ball thief if there ever was one.
