Answer
Pet-friendly waterfront camping exists near Ocean City, Maryland—with leash, fee, and count rules that change by park. Bay resorts such as Castaways / Sun Outdoors Ocean City have marketed dog-beach style amenities; many other private parks allow pets on designated loops only.
A pet-friendly campsite does not unlock year-round Ocean City ocean-beach access—Town seasonal dog rules still apply. Assateague adds wildlife and food-storage constraints.
Confirm the current pet policy on the property page, then cross-check Pets FAQ and dog beach rules.
