I'm currently feeding Jester Fromm's Beef Frittata and Veg. He's had some tummy issues but this seems to be working. My question is should I be adding Digestive Enzymes to this food? I believe Fromm already has some probiotics in it. Is too much probiotics a bad thing? I also add a dollop of pumpkin. He seems to poop A LOT but it is formed so I'm questioning the my additions. Thanks!
