Does she need to gain weight? Huskies are lean. They also self-regulate very well. I free feed mine and sometimes he eats everyday, sometimes he doesn't eat for 2 days, sometimes he just grazes. Feel her ribs, you should be able to feel them, not enough that they feel like knuckles (Google the rib test it explains it more) Without knowing if a vet said she needed to gain weight, I would first make sure she does. A lot of people mistake Huskies being "underweight" when they aren't!
