Interesting. I don’t think he’s sensitive to chicken then since he hasn’t improved on the rabbit food. That sounds like our rottie right now. He’s still recovering from a nasty reaction to his last chemo treatment. The drug did not agree with him at all. I think it killed off everything in his gut. We’ve been feeding him 3x a day with probiotics and enzymes in every meal. We had him on Nutrisource Weight Management for the high fiber (12%) which helps his diarrhea. Now he’s got mostly solid poop with the runny stuff at the end because we switched him to the Earthborn Holistic Primitive Natural (2.5% fiber) with no transition time. He just decided he didn’t want to eat the Nutrisource anymore. I was thinking that fiber might be the issue with your guy but that doesn’t make sense either. You tried 2 higher fiber foods: Orijen at 6% and NVI at 7%. I’m kinda stumped. Hopefully the Perfect Form will start helping. After you run out of NVI you could try NV Prairie LBP to see if he does any better with grains. I also wonder if he might do better on a dehydrated food like Honest Kitchen. It might be easier on his digestive system than kibble. Sorry I can’t be of more help. Those are just some thoughts I had. It sounds like all you can do is trial and error right now until you can definitively rule out parasites again.
