I feed my dogs premium grain free food too and I supplement their food with Nupro. I cannot stand the smell of fish oil but it does make an excellent supplement for their skin and coat. Another option is olive oil which I've also tried for my sibe but stopped giving it after he started getting softer stools as a result.
More frequent shedding can be the result of climate for sibes living in warmer areas. When we lived in WA state our sibe blew coat twice a year, but since living in FL for the past 14 months he has blown coat 5 times in the past year all due to the much warmer climate. And then of course no two dogs are the same and while the majority of sibes blow coat twice a year there are a number of huskies that smaller amounts year round.
My best tools are my high velocity dryer and my undercoat rake. Having a force dryer makes life so much easier although I know they are a little on the more expensive side, but I would never want to go through a coat blow without one!
