Yes, you can camp with dogs at Delaware Seashore State Park. However, there are some restrictions and rules you need to follow. Pets are allowed in designated areas of the campground, and they must be leashed and cleaned up after. During the summer season (May 1 to September 30), dogs are not allowed on the swimming or sunbathing beaches. However, they are allowed on non-guarded beaches and other areas of the park.
