This is somewhat similar to a concept I pitched for the Kennel a while back. Not as a production building that unlocks dogs, but as a passive defense that barks at any Allied player within range. Nothing else to it really, just a small building that barks like crazy when Allies get too close. Spies, engineers, Tanyas, etc... Where are they, specifically? Well, that is up to the vigilant Soviet team. The Kennel will point you in the right direction, but that's about it. Oh, and Allies, does that sound annoying to you? Don't worry, because it's the weakest structure in the entire game, so sending someone to destroy it in the early game is a valid tactic.
(DISCLAIMER: This was just something I pitched a while ago, and does not in any way reflect the plans or opinions of the APB team.)
