A nude sunbather is suing for the right to bask "au naturel" with his rat terrier, Cheekies, at his side. The man claims that the dog should be allowed with him because he suffers form post-traumatic stress disorder.

Former bodybuilder Mark DelCore, says sunbathing is a great for a skin condition he developed after exposure to World Trade Center toxins while leaving a lower Manhattan gym.

DelCore, of Forest Hills, Queens, favors a "clothing optional" beach near Kismet, on Fire Island. But officials at the Fire Island National Seashore say Cheekies is not welcome.The park allows only guide dogs on its swimming beaches. DelCore says his dog's healing presence qualifies him as a "service dog."
