Well this is just my take so you can always take him to the vet if you're worried but I only feed Ollie(who's 5 months old) 3 cups a day and his weight and body condition are ideal.
Maybe it's just too much food and he's not hungry? 6 cups(unless that adds up to a different amount in Canada, I don't know metric) seems like A LOT to me.
Especially with a super rich food like Orijen, they don't need to eat as much... If it were say, science diet or another low quality food like that then yeah I could see needing 6 cups a day. And if he's getting less exercise because of winter then that could possibly also explain a drop in appetite I think.
