I don't think you'll find anyone here who's ever fed the Innova that won't recommend it wholeheartedly. They not only have manufacture some of the best quality feeds from any perspective, they are also one of the most ethical when it comes to the animals that help develop their products. They are rescues, well loved and cared for in comfy, homey areas with lots of play time and interaction indoors and out and they are retired after a relatively short time and adopted into "real" homes!
As long as your husband isn't feeding her junk it wouldn't be such a bad thing to give her a treat from the table every now and then, but it's easy, especially for the small breeds, to get spoiled on it and refuse to eat anything else. It's hard to get the spouses to listen sometimes, but about the only thing you can do is try to explain to him that she's not getting a balanced diet and it's going to have an adverse effect on her quality of life, and even the length of her life, at some point.
