“Desperate Housewives” actress, Nicollette Sheridan, and “Exorcist” head-turner Linda Blair, were supposed to eat dog food during an event promoting “Dine With Your Dog Day.”

“This is not ‘Fear Factor,”‘ Sheridan said Thursday, balking at the idea of downing dog food.

Blair also declined, explaining she’s a vegetarian. But “Little House on the Prairie” actress Melissa Gilbert was game and scooped up helpings of doggie morsels.

Acid-tongued fashion critic Mr. Blackwell was on hand to applaud the best-dressed bow-wow and a pet psychic read paws.

Former “Eight is Enough” TV patriarch Dick Van Patten, whose Natural Balance dog food company was behind the event, said he wanted to show dog lovers how delicious pet chow can be.

The gathering celebrates the bond between man and dog by encouraging pet owners to share a meal with their dog, Van Patten said.

On Saturday, U.S. pet stores will be hosting special events to honour dogs big and small. Some sales proceeds from participating brands, including Natural Choice, will be going to animal shelters, Van Patten said.

“We hope to raise a lot of money for local animal shelters to continue their important efforts to give humane treatment to man’s best friend,” Van Patten said in a statement.
