@greek I used it for awhile with mixed results. My dog, Brembo had very soft stools when on it and always seemed to be itching. Note that I am always using more than one food, so I believe I was alternating the Duck and Sweet Potato with the Pork and Applesauce.
I was feeding about 1.5c 2x a day (so 3cups a day total), so I cut back on the food a little and the stools were still soft and the itching was still present. I changed the Pork and Applesauce to Fromm grain free beef frittata with better results.
Eventually I switched back to all grain free. I now alternate between the Beef Frittata, Surf and Turf, and Salmon somthing. I feed almost 4 cups a day and his stools are nice and firm, and he has minimal itching.
Best advice? Try it. Start with a small bag. Is your dog already on Fromm? If so, no transition (weaning) will be necessary. Pay attention to stools/itching. Good luck!
