Let slip

Before they were the dogs of war that warmongers would let slip, they were the puppies of war.
Breeders picked from the best lines of dogs of war to produce them, breeding for the best attributes of war.
Showing off their selections at dogs of war shows, working out deals with other breeders to reinforce bloodlines.
Feeding them puppies of war chow to help them grow big and strong and healthy.
Training them to be obedient, as long as they remain on the leash.
But when let slip, all chaos results.
And not just scattered squeaky toys and pissed carpets.
