From Command and Conquer Wiki
During the Great World War II, in order to guard their complexes from spies, the Soviets trained and kept attack dogs. In order to sustain their population, specialized structures called kennels were constructed. The kennel was the place where, when not on duty, dogs could rest and eat before their next assignment as well as where Soviet trainers could train their dogs.
[edit] Red Alert
Attack dogs were also used in the Great World War III, although kennels were no longer needed; the dogs were trained in the barracks. The attack dogs were mostly used to guard Soviet bases from infiltration by Allied spies. However, the Allies saw the potential of attack dogs and began to use them too, although in much smaller numbers than the Soviets did.
[edit] Tiberium
With attack dogs no longer regular military units, the kennels were withdrawn from use.
