All Delaware State Parks: Dogs are not allowed on beaches that have been designated for swimming or surfing. Dogs are, however, more than welcome to join their owners in regions marked for surf fishing. Owners are required to clean up after their pets.
Rehoboth Beach: It is illegal for dogs to run at large at any time. The city has both a leash law and a pooper-scooper law, both of which are enforced. Dogs are prohibited from the beach and boardwalk from May 1 through September 30.
Lewes Beach: From May 1 through September 30, dogs are only allowed on Lewes Beach before 8:00 a.m. and after 6:30 p.m. During the off-season, dogs are allowed unlimited access. Owners are responsible for keeping their pets on a leash and for any and all clean-up duties.
Dewey Beach: One of the very few towns on the Eastern Seaboard to permit dogs to enjoy the sandy beach, Dewey Beach has only a few restrictions for dog owners. The times at which dogs may enjoy the beach are limited during the summer season (they are not permitted on the beach from 9:30 a.m. to 5:30 p.m.). Dogs must be under control at all times, and, of course, their owners must clean up after them. The summer season is the period beginning on May 15 and ending on September 15.
Bethany Beach: Dogs are banned from the beach and boardwalk from May 15 to September 30. Pets are allowed access during the off-season, but owners must keep them on a leash and clean up when necessary.
South Bethany: Dogs are banned from the beach and boardwalk from May 15 to October 15. They’re otherwise welcome, provided owners keep them on a leash and respect cleanup rules.
Fenwick Island: Dogs are banned from Fenwick Island beaches from May 1 to September 30. During the off-season, pets are allowed access, though owners are responsible for cleanup work and must keep pets on a leash.
