The Hotel Pennsylvania in Midtown is going to the dogs.

A-list pooches and their owners are gathering there ahead of the Westminster Dog Show.

They're getting the star treatment at the hotel's "Room to Grow S'paw."

There's even a special concierge to deal with requests for the doggie divas.

"They're like models, and you think models don't eat? Guess what, cheeseburgers are classic. Hold the onions, because onions are not good for dogs. So believe it or not, they'll have them for the dog, make them feel comfortable before the show, and they're ready to go today," said Jerry Grymek, a doggy concierge.

The 141st annual Westminster Dog Show runs today and tomorrow at Madison Square Garden and Pier 92.
