I need help figuring out what to feed my 7 month old Male doberman. He has had stomch issues ever since we brought him home and tried many dry food recent one being sensitive stomach pro plan puppy with no success. We treated him for giardia just to be sure and ruled out parvo long time ago. His symptoms are gas, bloating, abdominal pain, diarrhea. I know that can all happen when introducing new foods but we have been on the latest sensitive stomach pro plan formula for 2 weeks with no improvement just worsening diarrhea. The only dry food he did somewhat okay on was Pro plan giant puppy. He's currently on home cooked chicken and rice and is doing amazing with diarrhea instantly stopping. My question is should I keep him on chicken and rice indefinitely and should I be adding supplements if yes what kind? Can I feed him raw chicken as well or do I need to slowly introduce that to him so he doesn't get salmonella poisoning? Thank you for all your help!
