Night one showcased the best of the Hound, Toy, Non-Sporting, and Herding groups who took center stage Monday at New York City's Madison Square Garden.

The fierce and fluffy pet competition was all business in the ring, but in the benching area backstage, groomers and handlers spent hours primping and prepping their pooches.

Baby Lars the Bouvier des Flandres, the best of his breed, won the Herding group.

Burns the seven-year-old Longhaired Dachshund snagged top prize in the Hound group.
