The wildly popular National Dog Show's 15th annual Thanksgiving Day special is here. From 12 noon to 2 p.m. in all time zones across the U.S. on Thanksgiving Day, NBC will air the annual canine competition, which will take place Saturday and Sunday in Oaks, Pennsylvania.

"The shows, sanctioned by The American Kennel Club, will help raise money for a variety of canine-related causes," a statement on the show's official website read. The show will take place at Greater Philadelphia Expo Center from 8:00 a.m. to 6:00 p.m. Saturday and 8:30 a.m. to 5:00 p.m. Sunday.

The NBC special will be hosted by award-winning actor, author and Broadway star John O'Hurley.

"For 15 years, the 'National Dog Show Presented by Purina' has been at the forefront of the purebred dog world," O'Hurley said. "I'm proud to be a part of a legacy that celebrates such a rich history. I look forward to seeing all the dogs and families, who come out to join us on my favorite day of the year."

Three new breeds sanctioned by the American Kennel Club — the Pumi (herding group), the Sloughi (hound group) and the American Hairless Terrier (terrier group) — have been added this year. The total of recognized breeds and varieties for the competition this year is 202.

Last year, Good Time Charlie, a 4½-year-old Skye Terrier, was named Best in Show from among the seven group winners.
