I have 2 husky mixes and used to have 3 purebreds and yes they shed 24/7 (well pretty darn close). I brush everyday and it does help. They are on a good diet which helps some too. They do shed more often twice a year during their blow out and I too think that being inside makes them shed worse (I do not know for sure as I never had any be outside dogs) but it is logic going from air conditioning (not too cold though) to the hot sun, then in winter going from heat to freezing. But I think thier hair is worth the love.
