i have all mine on 4Health right now and our male has a sensitive tummy and so far he's been doing fabulous on it!! I also mix in some Taste of the Wild so he's getting the 4 star food plus a little bit of 6 star. I can afford to feed taste of the wild solely so i just buy the little 5 lb bags and the bigger bags when i can and they're good. bout a 1/4 -1/2 cup of the taste of the wild with the 4health which for him is about 3-4 cups. he hasnt been sick once and his poops have been solid for the first time consistently in his 6 years.
