America's Top Dog

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?

A fur missile, a veteran K-9 named Murphy and a small civilian underdog compete.

Two civilian underdogs take on the professional pooches in an epic clash of K-9s, as a brash boxer and a peppy pit bull attempt to be leader of the pack

The youngest dog in the competition sets a fur-ious pace; the more experienced dogs must take matters into their own paws or a youngster will 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?
