She’s got that hang-dog look! Pooch purses all the rage

This doggie bag is hotter than a Birkin.

The city’s most fashionable dog owners are snapping up “puppy purses’’ this summer to tote their tiny pooches.

“I bring him to work every day, and in the morning, he sits on it waiting to be placed in it,” said ex-model Rachelle Garzia, who had her 1-year-old Brussels Griffon Shih Tzu mix, Frank, slung over her shoulder in one of the stylish bags on East 30th Street and Park Avenue yesterday.

Garzia, 29, a brand-strategy manager at the Gansevoort Hotel Group, said, “If it’s not sitting out, and he sees me pull it out of the closet, he goes nuts, wagging his tail.

“So I’m pretty sure he loves it.”

The Petco store on the Upper West Side said the pouch pooch is so popular that they’re sold out.

The device — a harness that’s fashioned like a purse, with a casing to cover the dog’s chest and allow its legs to dangle in between the straps — goes for about $70.

“They’re very popular, and they sell out very quickly,” said a Petco saleswoman, noting two women came into the store Wednesday asking for the sold-out purses.

Garzia said she started carrying Frank around in the open carrier in May because it was getting too hot for him in an enclosed dog bag.

She said she purchased her puppy purse online at bitchnewyork.com, where embellished pouches can sell for up to $100.

The purses come in small, medium, large and extra large, but are typically fashioned for dogs that are 2 to 3 pounds, such Chihuahuas and Yorkies.

The largest model is for “6-plus pounds’’ and appears to be mainly for longer dogs.

Critics say the fashion statement is distressing to the pups who are suspended in the air with their legs dangling.

But Garzia said she never keeps her dog in the carrier for more than an hour.

“He’s pretty vocal,” she said. “He would probably start whining if he wanted to get out, or needed to relieve himself.”
