Hi Boris-Frank,
Did you slowly introduce the new Racheal Rays kibble over 7-10 days, when you try another new kibble slowly introduce over 7 days? Bloody stools can be from food sensitivities, he’s probably sensitive to any ingredient in the Rachel Rays kibble & has reacted this happened with my boy when I first got him I thought he had Parvo it was awful all he was doing was diarrhea red blood, later found out he has IBD & is sensitive to certain ingredients..
Look at “Canidae Pure Petite small breed formula’s have limited ingredients & Canidae All Life Stages formula’s, Canidae is for dogs with sensitive stomach/bowel, my boy does well on Canidae All Life Stages “Platinum” & “Canidae Pure Wild” Boar formula.
Canidae grow their own vegetables & source the other ingredients from local farmers…… here’s Canidae’s web page https://www.canidae.com/dog-food/products
