The Furminator brushes work really well at getting out tons of dead hair. I have purebred pugs and I know how much they can shed! I try to take them to groomers on a regular basis just for basic baths and they do a great job at brushing them out.
I've also found that when they are on a diet high in omega 3 fatty acids, their coats are much nicer, more plush, and they shed a lot less. You can add a fish oil capsule to her food once a day to up the omega 3 content and you might see a difference within a few weeks. My dogs are older, so I am feeding them a prescription diet from Hill's called j/d - it has fish oil already in it and a very high level of omega 3s to help with inflammation from arthritis. I've also noticed that when they are on it, they shed a lot less. Some of my pet owner clients that have had their dogs on it for arthritis have noticed how much nicer their coats are too. I don't think it would be an appropriate diet for a still-growing 6 month old puppy but you can try just adding the fish oil capsules to her food for now.
