Suitable for (our) sensitive dog

I read a review on another variety of Pro Plan, in an owner writes that her dog the food absolutely can not tolerate. So experiences differ, but mine is very positive. Our dog, now about 10 years old, had an extremely sensitive stomach, which has also continually pointed over the years has always been. Meanwhile us only two varieties are known food that he can withstand any problems and the "stay inside" also. That's on the one hand the cheap YES! Lining from the supermarket, on the other Pro Plan. The latter he tolerates this still the best and it seems to him very well to taste. Hence from me 5 stars, but ultimately has to probably everyone by trial and error to find out what is appropriate for your dog.
