Here's the relevant rules text from both classes.
Bloodrage:
Bloodrage counts as the barbarian's rage class feature for the purpose of feat prerequisites, feat abilities, magic item abilities, and spell effects.
Ulfen Guard's Rage:
Rage (Ex): An Ulfen Guard is trained to harness her brutish nature while in combat in the defense of her charge. This works as the barbarian ability of the same name. An Ulfen Guard’s class levels stack with any other classes granting this ability for determining the effects of rage powers and the number of rounds per day the guard can rage.
Ulfen Guard Rage Power:
Rage Power (Ex): The Ulfen Guard can select a barbarian rage power for which she qualifies, adding her Ulfen Guard level to her barbarian level to determine access. This guard dedication can be chosen up to three times.
