America's Top Dog - Season 1

A veteran K9 nicknamed "The Wonder Mutt" figures to be the favorite, but will he be taken out by the younger, hungrier competition? His challengers include a police dog with hundreds of narcotics arrests and a civilian trick dog who just might be the most talented tail-wagger in the whole field.

A third generation police K9, and a civilian underdog built for speed are among the pooches who face off in a competition that comes right down to the wire. Who will get the last woof?

Will the "Fur Missile" take off? Will a veteran K9 named Murphy lay down the law? Or will a the competition's smallest civilian underdog shock them all?

This time not one but two civilian underdogs take on the professional pooches in an epic clash of K9s. Will experience win out, or do a brash boxer and a peppy pitbull have a real shot to be leader of the pack?

The youngest dog in the competition sets a fur-ious pace. Will the more experienced dogs take matters into their own paws or will the youngster bring home all the biscuits.

Among the K9 combatants are a dog who once took down a crossbow-wielding creep, a pooch whose trainer is allergic to him, and a team with inspiration on their side. Who will emerge lick-torious'

It's raining cats and dogs but the K9 combatants show their gladiator spirit, battling through bad weather and tricky tunnels right down to the final seconds.

With some of the most decorated doggies ever to set paw on the K9 Combine, it could be a record-breaking night.

Tonight's lineup raises burning questions: Can old defeat young? Can skill beat experience? And where the heck is Catahoula?

A doggle-wearing K9 faces some tough competition including a Connecticut K9 who's ready to declare war and cancer-surviving civilian underdog named Bruce.

Six winning K9's and one champion underdog battle it out for 25K and the bragging rights for the ultimate title of America's Top Dog.
