The season's "Top Dog" winners are back to see if they have what it takes to make it to the winner's circle once again.

America's Top Dog

One Top Dog Left Standing

The runner-up pooches from the season are back for redemption; it'll be a record-breaking night as these hungry pups compete for the last remaining spot in the grand finale and a chance to become America's Top Dog.

Redemption on the Line

A bulldog/pitbull mix that was rehomed five times, an Australian cattle dog with two titanium knees, a pitbull that went from police K9 to farm dog, "Top Dog's" first ever Siberian husky, and a rookie K9 cop are all ready.

Pound Pups to Top Dogs

An invasive mussel-sniffing working dog will take on four underdogs: a pitbull with a Hollywood bloodline, a dock-diving super mutt, an ex-narcotics detection black lab, and an all-female team ready to show the boys who's boss.

Super Mutts and Super Sniffers

Two police canines, a cancer-detecting lab, a border collie bat dog and the ultimate underdog, an 11-year-old completely deaf pitbull, battle it out in the combine.

Super Dogs

A diva of a Doberman, a police K-9 with a fear of water, an American Bully underdog, an avenging Rottweiler and an explosives detection dog all put their best paw forward, but only one will stay the course and take home the coveted Top Dog title.

Off Course Canines

A tutu-wearing Rottweiler, a partially deaf cattle dog, a speedy mixed breed, a beer-retrieving trick dog and a police K-9 favorite from Season 1 vie for a spot in the Dog House.

Can't Keep a Good Dog Down

A Frisbee fanatic border collie, a water-fearing Doberman, a tiny but feisty terrier, a movie star German shepherd, and a police K9 compete to move on to the Dog House for a chance to win the Top Dog title.

New Season, New Dogs

Police and civilian K-9 teams are tested on their speed, agility, scenting ability and teamwork by completing a series of tasks on obstacle courses designed by experts to mimic real-life challenges that the furry heroes face every day on the beat.
