In celebration of man’s best friend and with the glamour only Beverly Hills can provide, the star-studded competition will be co-hosted by award-winning TV personality, author and Broadway actor John O’Hurley and American Kennel Club-licensed judge and expert analyst David Frei.

Emmy Award-winning journalist, author and TV personality Maria Menounos will welcome two and four-legged celebrity guests on the red carpet, NBC Sports correspondent Mary Carillo will report from inside the show ring and “American Ninja Warrior” host Akbar Gbajabiamila will provide behind-the-scenes access as digital contributor.

NBC airs the third annual “Beverly Hills Dog Show Presented by Purina” on Easter Sunday, April 21, 10 a.m. to noon.

This year’s celebrity guests will include Mario Lopez, Ashley Tisdale, Shaun White, Bo Derek, Parveen Kaur, Michaela McManus, J.R. Ramirez, Melissa Roxburgh and Triple Crown-winning jockeys Victor Espinoza and Mike Smith.

Hosted by the Kennel Club of Beverly Hills and produced by NBC Sports, “The Beverly Hills Dog Show Presented by Purina” is a new breed of dog show and a new holiday tradition for the whole family.

Before more than 1,500 dogs representing 200 eligible breeds and varieties face off for the coveted Best in Show title, the canine competitors will mingle with celebrity guests and strut their stuff on the red carpet. For the main event, each group winner will walk the show’s unique runway for the Best in Show judge to determine which dog has what it takes to be champion.

Last year, King, a 7-year-old wire fox terrier from Brazil, was crowned Best in Show. He later went on to win Best in Show at the prestigious 2019 Westminster Kennel Club Dog Show in New York.

In 2017, Ripcord, a Doberman pinscher from Houston, was awarded the Best in Show title.America’s foremost authority on all things canine, David Frei is a natural choice to serve as host and expert analyst for the National Dog Show Presented by Purina. An American Kennel Club-licensed judge who has officiated dog shows all over the world, Frei hosted television coverage of the Westminster Kennel Club Dog Show for 27 years.

A successful former breeder/handler/owner, he is proudest of the work his therapy dogs have done at the Ronald McDonald House of New York, the Memorial Sloan-Kettering Cancer Center and the New York VA Hospital, among other health-related institutions. Frei’s first book, “The Angel by My Side” (Hay House Publishing, 2002, with Mike Lingenfelter), claimed two Dog Writers Association of America (DWAA) Awards.

His latest book, “Angel on a Leash” (BowTie Press, 2011), also a DWAA award winner, tells of his years of experience and work with therapy dogs. In 2018, Frei was inducted into the Dog Writers Association of America Hall of Fame.
