“We have it down to a science,” the canine concierge, Jerry Grymek, said of the hotel, which has been hosting Westminster competitors since the 1990s. “People have rituals to make their dogs feel comfortable.”

Mr. Grymek has rolled out a red carpet for one dog, he said. And furnished an opera singer to serenade an Italian Spinoni that was fond of the music.

He has picked up food: a slice of pizza, a chicken sandwich, “six McDonald’s cheeseburgers; hold the onions.”

And hired dog acupuncturists and psychics. (The psychics informed owners that their dogs were nervous, and did not wish to eat beans.)

He has also fetched cots — for the coaches, not the dogs: The dogs get the beds. “The owner wants the dog having optimal sleep,” Mr. Grymek said. “They’re in the show, after all.”
