Sounds like you’re giving him a lot of different things all at once. All good for him but many of them are potential allergens. I would slow down a little. many people on here have dogs with chicken/fowl allergy so I’d stop the chicken for sure right now. I would also stop feeding Blue anything. You’ll see lots of complaints about that brand on this site. Put Blue in the search bar. You may need to go back to whatever he was eating when you got him if he was ok while eating that, even if it wasn’t a great quality. Start adding a new food, and only one, and wait a week or so, see how he reacts. Then add another food, see what happens. This way you can tell what’s bothering him. As far as the stool, start him on a probiotic. My dog can eat whatever is put in front of him but some dogs with a more sensitive stomach may need a little help with the transition. Some dogs have trouble especially going from, say, a 2 star food right to a 4 or 5 star. Go slow, you can work your way up to good kibble and raw. Good luck, hope this helped.
