Unfortunately, our dog (German Shepherd-Doberman-hybrid), which is now quite getting old (> 10) has a very sensitive stomach, most foods cause diarrhea or vomiting. The lining of Pro Plan is one of the few brands that it can withstand. Elsewhere was sometimes criticized that the food contains too many preservatives, but we can be choosy because hardly. Each food that the dog tastes and especially more than 10 minutes there is, has ever guaranteed 5 stars from us per se.
