Also a pain for Allied GIs. :P

"Attack Dog - Specially trained Siberian Huskies, Attack dogs are extremely effective against infantry but are completely worthless against vehicles and structures. Additionally, Attack dogs are your first, best, and only line of defense against Allied Spies. You'll want Attack dogs guarding your base at all times."
Oh I have no doubt that they would protect us if we needed them too.
Especially the older Husky. She seems to understand such things really well.
