What's a gearhead pet to do on Halloween? There are plenty of choices for people (our favorite being Human Tire Barrier), but it's a little harder for our pets. That is unless you're extremely clever and can turn some cardboard boxes into a TANK DOG.

The creator or of this awesome, tracked costume created the tank from cardboard, paper clips (for the tracks) and even has a real working weapon. Needless to say, TANK DOG destroyed all the puppy pirates and kitty karate masters at the local Petsmart Howl-o-ween costume contest.
