Will your armored husky from the dawnguard questline leave your service if you become a VL at the end of the questline?

No, They were going to let you put a death hound collar on your huskys to turn them undead, But the content got cut. Like upgrading your strongholds.

Stop Freaking Complaining, its annoying, and how would you know that they were going to let you do that?

Maybe if he complains enough, Beth will break down and add the features they left out... Unless, the Xbox release is not really a release, and just a stage two beta?! using us to perfect the game for the PC/PS3 release.

It is truly amazing how Sage knows content got cut.
He obviously works at Bethesda, how else would he know?
