We went thought he same same with Logan, did find out quick that grain free was not going to work for him, it was to rich. I also think lentils and peas were causing some of the problem.
I do know that when I would try a new food and the loose stools would start I would take him off the food. I wasn’t giving it enough time. We had the best luck with Purina proplan focus but I’m taking them off of it and slowly adding Annamaet Encore. I have a lot of trust in the company. I do know that overfeeding can cause issues. Have to tried adding pumpkin to the kibble? The plain not the one with spices that is used for pie. You may need to go with a home cooked diet for awhile to get his tubby to settle down. There are several excellent fb sites telling you how to do it. Have you added probiotics? natures farmacy has a good one. For now I would add probiotics, a tlb of pumpkin to each feeding and make sure you aren’t overfeeding.
