Here’s the luckiest pooch in New York.

A hero cop jumped into the frigid Hudson River yesterday and saved a 4-year-old German shepherd who had fallen off her owner’s boat, police said.

Chloe had gotten stuck under a dock in the southern part of the Chelsea Piers marina when Detective Matthew Sherman, an NYPD scuba diver, put on a wet suit and made the rescue. “She was stuck pretty good,” police on the scene told The Post.

“They had a diver ready to go, and he jumped in and got her unwedged,” said Chloe’s owner, Mark Stoss, 42. “The dock was floating up and down, and I thought it was going to crush her.”

The dog lives with Stoss, Stoss’ fiancée, Isabel Anaya, 31, and another German shepherd on a 50-foot catamaran that has been docked at Chelsea Piers for about eight months.

The dog fell from the craft at about 10:30 a.m. and swam around in the 20-foot-deep water for about 30 minutes before Stoss — who had been away at a court appearance, where he successfully fought a dog-walking ticket — spotted her splashing.

“That sounds like my dog,” Stoss recalled thinking. “I looked everywhere, and I couldn’t see her,” Stoss said. “Finally, I looked in the water, and she was stuck under the dock. I started screaming, ‘Call 911! Call 911!’ ”

Some passers-by tried to help before cops arrived.

“I looked and saw the dog trapped on an I-beam, too scared to move,” said Joe Guarascio, 27. “I stuck my arms into the water, which was absolutely freezing . . . I almost had her. She was whimpering.”

After the harbor unit arrived, Sherman went under the dock and was able to coax the dog out and put her onto a Zodiac inflatable boat. He had help from Detective Michael Cocchi, who manned a rescue line, and Detective John Drzal, who was operating the boat.

“The NYPD was amazing!” Stoss said. “Their response and helpful officers were amazing.”
