That is quite a list, I would go to a homemade diet. I would also consider consulting a homeopathic veterinarian or an animal nutritionist….or a specialist (dermatologist/allergies) depending on your treatment preferences (if you haven’t done so already) and if the problems continue.
Have you tried a little boiled hamburger and white rice?
See my posts in other threads for links that might be helpful.
Ps: I had a pup that had loose stools till she was about 8 months old…and then it just stopped. I had tried various foods, I never did get it diagnosed.
I wondered if it had to do with all the vaccinations she had received and maybe her immune system was out of whack.
