they didnt live long enough to recieve them
From what I understand, While the Russian where training these dogs, they would use their own vehicles but made them look like german Half-tracks and supply trucks. However during combat, the chaos of battle would frighten the dogs and rather than run to the german vehicles they instead ran to Russian vehicles and positions. Turns out the russians trained they dogs with vehicles that used Diesel, while the Germans used Gasoline in most of their trucks. When they dogs were startled by the loud noises of explosions and gun fire, they'd run to the vehicles that smelled like Diesel.
