Wardogs are the ultimate fire-and-forget weapon. The moment you see an enemy unit wavering, unleash the mutts on them to really turn the screw. Once the handlers have let the slavering brutes go, run them back to a place of safety then hit the withdraw button. This keeps them intact for the next battle. The dogs will chew their way through routing enemies without any further prompting from you, leaving you free to concentrate on spreading the rout. Good doggies!
