Poor Sequoia! She is such a gorgeous girl, I hate to hear she's having problems. Could it just be the weather/season? August usually isn't a good coat season for any husky.
I think you know we recently got Jack, and his fur sounds alot like Sequoia's. As far as the scruffiness, Sue said he's just in between coats, & his sisters used to grab him around the neck & broke the hairs off. But he's losing guardhairs like crazy, & Sue told me to pull them out, which he seems to enjoy... His fur is much oiler than Star's or Sherman's ever was. I'm kind of at a loss about what to do too. I treated him with a dog conditioning/finishing spritz after his last bath & he looks better- more shiny & softer. BTW, he ate Purina Professional before & has been on Canidae since he's been here for the past month. Star decided she hates Canidae (after eating one 40-lb bag with no problem ), so she's back eating Science diet. I know a lot of people knock it, but she's done well on it her whole life.
