He weighs considerably less than all-time New York Knicks basketball star Patrick Ewing, but he wowed the crowd at Madison Square Garden.
Costello, an Alaskan malamute who lives in Lockport, was runner-up in the working dog group at the Westminster Kennel Club dog show in New York City on Monday.
The distinction came on the heels of being named national champion at the American Kennel Club/Eukanuba National Championship in Tampa, Fla., last month.
Being named top dog in the country was a huge kick for the 3-year-old and his co-owner/trainer, Sandra D'Andrea, but doing so well at the prestigious Westminster Kennel Club show carried its own weight.
"Everybody wants to win at the Garden," D'Andrea said Wednesday after driving Costello back from New York City. "The place was packed. It was a huge thrill."
Costello came in second in the working group, behind a Rottweiler. A mastiff was third, and a Portuguese water dog finished fourth.
Officially known as Nanuke's Snoklassic No Boundaries, Costello is co-owned by a Michigan couple and a California woman.
He was named Costello -- and his brother named Abbott -- because they resembled the classic comedy team of the 1940s, D'Andrea explained.
Abbott is a four-time regional champion, and his father, Tyler, is the nation's top winning malamute, with 73 best-in-shows under his belt, including the 1998 Westminster show.
"They've all enjoyed going on the road and showing off," said D'Andrea, who lives in Lockport. "I gave Costello a cheeseburger, and he's happy."
Costello was playing outside Wednesday, but on Saturday, he is off to another dog show, this one at the Buffalo Convention Center.
"He's looking forward to it," D'Andrea said. "Another show, another cheeseburger."
