I showed dogs for a long time, and have set up at shows next to every breed possible. I'm not proud to admit that my breed sheds more than any other I've run into. I've had as many as 5 adult Kuvasz living in the house with me at any given time so the answer is no ... if the dog hair I was tossing into my washing machine didn't kill it, the hair of 1 Siberian won't come close.
The good news is that right now he's probably loosing his puppy fluff. Once that is done he will shed a bit all year round, then once or twice a year he will have a "blow" when he loses all of his undercoat. Get yourself a rake - designed for removing undercoat, and remove as much as you can outside. My one last Kuvasz is blowing coat now.
This is what it looks like after I've raked and blow dried him. Bear in mind, this is just the first rake. It takes 3-4 weeks to completely blow coat ... so I have a pile like this every week for 3-4 weeks.

Vacuum cleaners are another story. I've killed scores of those!!
