Keep in mind that for NPC summons you have to reverse your hollowing and be in human form to even see their summon signs. They'll be very obvious gold and black marks on the floor somewhere in the nearby vicinity of the boss's fog gate, but as others said not every boss has an NPC buddy you can summon and some of the summoned people have specific conditions that have to be met for them to be available. They'll follow you wherever and help you fight things, but if you're having enough trouble with a place that you need help from an NPC then you should either probably not be there at your soul/gear/skill level.Also, for when the time comes, I suggest nobody bother with NG+ if they can't handle painful grinding. This shit is brutal, well over 30 attempts on the boss before I finally got through Anor Londo in NG+.
