InkedMarie,
Dogs who have or have had cancer ALSO desperately need low glycemic foods without simple carbs, because cancer feeds selectively, preferentially off sugar vs. fat or protein or fiber. After a cancer diagnosis, diet is an incredibly important part of the most successful recommended *treatment*.
Given that an incredibly high percentage of all dogs and cats suffer at some point from cancer, you are also really helping those dogs and their guardians with the list. By one statistic, half of all dogs and cats now die of cancer.
(Protein needs in dogs affected by cancer are higher because the body competes with the cancer for the protein, with the cancer robbing some from the healthy body, while dogs’ healthy bodies need protein for muscle & tissue repair and building.)
