India, Sept. 13 -- Actor Dylan O'Brien made a rare appearance on the runway during New York Fashion Week (NYFW) . However, he wasn't alone as the fashion event took a pup-tastic turn as the actor walked the runway with a dog in tow. He was walking for designers' Rachel Antonoff and Susan Alexandra's Best in Show in New York City. Akin to the dog shows that are popular in the West, the show featured several dogs that are up for adoption from a dog rescue in NYC. Dylan wore a red knit sweater with white design, that was paired with a red and white striped pants, and black loafers. He carried one of the fashion designer's signature beaded bags in the shape of a dog and even had a dog figurine attached to his pants. The 34-year-old was all smiles as he lead the puppy by a beaded leash and it hopped and skipped alongside him while trying to reach for the treats. Other celebrities who were a part of this fashion showcase included Nicole Byer, Edie Falco and Ali Stroker. htc...
