Are you maybe giving too many treats? She looks like a very small dog. If she is still pooping, she is still eating. Try cutting out the treats for a couple days. And try cutting back on the amount of supplements, in case they are decreasing her appetite. If her eating doesn’t pick up then, changing foods again may be what you need to do. My dogs didn’t like BB when I tried it, but that was years ago. Personally, I’ve heard too many stories of dogs getting bladder stones on it for me to want to feed it to a dog with crystals.
