Ditto, my Sam. Can your Sunny handle chicken now? (I went from Nutro Ultra--lamb, chicken, salmon--to Eukanuba Venison/Potato: instant relief. Just wondering what to do with three more bags of Ultra, and hoping he'll be able to tolerate it.)
I haven't tried him on chicken again yet so I don't know. My plan is to keep him on the lamb for several months and then try the chicken again and see what happens - I too have lots of chicken food I'd like to use up!
That's interesting about the intestinal bacteria being out of kilter, but I guess if the diarrhoea goes away with a change of food then the bacteria can't be the cause of the diarrhoea?
