We recently switched to Fromm Four Star Nutritionals dog food. My boys have been eating Life's Abundance for about a year, but I wanted to switch food to see if it would help Max with his coprophagy issue (it didn't).
Cooper has a very sensitive stomach and is doing quite well with this new food. Before we started on Fromm he would dabble in his food bowl, eat one piece at a time, walk away for a while, come back, etc. Now when I prepare his bowl he actually spins in circles! It's such a joy to see him really enjoy his meals. Max could eat anything.
The best part about this food is there is a variety of flavors all with the same formula so the flavors can be switched out as often as we want. Yesterday was Duck & Sweet Potato and today was Chicken ala Veg. The switch has never effected my boys' tummies. There is also a grain free formula.
I'm no nutrition expert but I believe this is a healthy food. If you have picky eaters, you may want to give it a try. There's nothing better than screaming "Who wants Pork & Applesauce?!!!" and having the boys run and almost knock me down to get to their bowls
