She loves those dirty dogs!

A Long Island hooker sold more than just sausage at her roadside hot-dog truck — using the truck to peddle her own flesh even though she’d been busted on the same rap eight years ago, cops said yesterday.

Catherine Scalia, 45, was arrested Thursday night when she offered the off-menu special to an undercover cop and took him back to her East Rockaway pad for some home cooking.

The mother of four pleaded not guilty to a prostitution charge and was held on $2,000 bail.

It’s the second time Scalia’s been busted for mixing sex and Sabretts. She and a pal were nailed in December 2004 for running a similar operation out of the hot-dog truck.

Cops recently discovered she was back in business after disgusted residents near her Baldwin stand complained she was handing out suggestive business cards alongside steaming kielbasa.

Titled “Strips-R-Us” and featuring a dated photo, the cards offer bachelor-party services, “one-on-one strips” and a “topless cleaning service.”

An undercover cop approached the stand Thursday and bought two hot dogs and water for $5 before the “specials” were announced.

Scalia took the cop back to her place and performed a striptease for $100 before unveiling the main course, police said.

“She agreed to manually stimulate him for an additional $50,” said Nassau County Police spokesman Kevin Smith.

She was slapped with cuffs instead.

Smith said that Scalia, who had a prior bust for DWI, did not have permits for hot-dog sales and that her camper-turned-brothel was illegal.

Her neighbors weren’t surprised by the bust.

“In the summertime she’s out in her bra and panties,” said nauseated neighbor Jem Velasco. “It’s disgusting. She’s filthy, she’s dirty. How could men take that?”

One neighbor said the men who exited the home appeared to have enjoyed their experiences there.

“They seemed pretty happy,” she said. “Now I can see why.”

In 2004, Scalia and her late co-chef, Rose Skorge, performed sex acts right in the same camper’s captain’s chair.

They advertised themselves individually as Roxy and Diamond and in tandem as “Double Delicious” until they were done in by an undercover cop.

“What do you want? It was a bad hot-dog day. I sold maybe $5 worth of hot dogs that day,” she told The Post after that arrest.

But she claimed she didn’t offer the cop sex, just a peek at her chest.

“I mean, what’s wrong with indecent exposure?” she asked. “Showing your chest — how could that be prostitution?”

She also said she had shown some restraint.

“I zip up when I see kids,” she said.
