All 3 of my dogs have been on Fromm Chicken a la veg for 1 1/2 years. One by one, they started having issues with their stomach (extremely loud gurgling in their intestines ) and some vomiting of bile...even with increased feedings. Talked to vet because episodes were increasing. He said sometimes you need to change foods every so often. I thought this was a little odd but..I changed to Fromm Duck and sweet potatoe and all 3 dogs have not had any problems at all since the change.
