I had an allergy panel done on him and the booklet lists the food and manufacters that make things he can tolerate. I tried boiled chicken . . . it didn't change anything and after a few days he refused to eat it. I do find it odd that he tends to sleep all day with no apparent issues, and then goes during the night.
I just gave him his dinner. About a teaspoon of the tuna he may have and he no sooner started to eat it and he had to go. I don't see how it can get into his intestinal tract that fast.
His history is he lived in a garage for a few years and was abandoned when the people moved. I can't help thinking that he ended up in the garage because of the diarrhea.
