I've heard that too much protein can give them soft stools...when I was giving my dog a lot of high-value training treats (chicken, roast beef), he had soft stools...
it went back to normal when we were done with our class...so maybe cut the meat topper back a bit, and see? I know it seems nice to give it to them, and they love it, but maybe it's the "too much protein" thing?
Oh, and if your dog has more of a "husky stomach", she may do well on something fish-based, I don't know if you've tried.
PS Storm is beautiful and seems to have gotten the big GSD ears. I've got a white shepherd/husky mix! :-)
