A lot of dogs don’t produce the digestive enzymes they need to digest everything in kibble, because in the wild their prey would have enzymes in it, but the process of making kibble kills all the enzymes. If I were you, I would switch to NutriSource Grain Free, for a grain free, they are a lower protein, and they seem to be easy to switch to for dogs with sensitive stomachs. Then I would add digestive enzymes, probiotics, and a spoonful of pumpkin to every meal. You may be able to cut back on those after a while because dogs do usually adjust after a while, but some dogs have more trouble adjusting than others. If you aren’t opposed to ordering online, Swanson’s has a great probiotic cheap, Dr Stephen Langer’s. They also have digestive enzymes at a good price. I would just give an adult human dose of both until he is doing fine, then slowly see if you can decrease the amount you give.
