I'm coming her to get some advice because it seems I cannot find a food my dog's stomach agrees with. We got him at about 7-8 weeks old and he is a pure boxer. He is now 6 months old. The breeder gave him to us and at that point he was currently on Royal Canin for puppies. Since then we tried switching him over slowly to Solid gold (bison) Wolf Pup, he still had very loose stools so after a month of that we tried blue buffalo (chicken). He seemed to like that food more then the solid gold but still had loose stools. Now we are currently on Orijen (chicken and turkey) he eats a lot less of it due to the amount of protein in it. But now we are seeing that he has thrown up his food at least twice in the past 3 weeks. We are also incorporating solid gold seameal, nupro dog supplement and pro-biotic miracle by Nusentia. We figured the pro-biotics and enzymes would help solidify his poop but it has not helped yet. Has anyone ran into these issues we are now thinking of moving on to either solid gold puppy lamb and rice or California natural lamb and rice. Our vet has checked his stools numerous time but doesn't find anything he stated the dog's stomach could be sensitive to the main ingredient in one of the food but he is absorbing and digesting his food properly. A few weeks ago we also tried the pumpkin because it is supposed to help ease the stomack but it didnt seem to help to much but that could be because of the food he had. Not sure. I have noticed that the pro-biotic has helped (recently the last 2 days) because his poop is starting to solidify. But sometimes he has hard stool at first and then the end of it will be very loose. Please any ideas will be appreciated. I'm running out of options. Thanks
