Loviatar had the Powder Gangers friendly with her for a while. I avoided doing the Joe Cobb quest in Goodsprings, and instead went to the prison and 'joined' their gang. They have a short questline of about 3 quests. In the end Loviatar switched sides and helped the NCR retake the prison. Then it was time to feast!
After that, the other Powder Gangers were always hostile.
One nice thing about a dog companion like Guts is that they are low to the ground, and won't block your shots. I liked summoning wolves and boars in Oblivion for that reason. Lions were nice too, until they jumped.

Yikes, that Deathclaw was close!
Blondie has the hottest table in town!
