Hey Johmel, most husky owners can feel their dog's spines. Its just the breed. There's nothing wrong with her. My husky has stayed the same weight all her life even though I free feed her. And most only nibble at their food as well, most are just not veracious eaters. In fact to me I feel like my new dog is fat because I got so used to Storm's body weight, lol.
As to the poll, I give my husky free access to feed at night (only time I can keep them separated and she used to choose to eat at night anyway). I feed my Beagle/Mt. Cur twice a day because he will overeat if I free feed. I like feeding him the smaller meals because it keeps him interested in food throughout the day as I train him.
