Debo update nr2. I think we found the answer thank to Hayley :)

Debo started to be sick Thur before Christmas,we took him to vet,got some tablets,he was fine for few days and day night after we started to mix his food into rice and chicken he was sick again. We put it down to treat me OH gave to him. Back on rice and chicken. Hayley suggested it could be food allergy. ,I was still convinced that it was something different. My OH said that maybe we should get back to f4ds,so we did. And he's fine. We still mixing it with rice and chicken but he wasn't sick for 3nights. He was on wainwrights turkey/rice. Thanks Hayley.

It's great to get these things sorted out, hope Debo continues to make progress, hopefully you have managed to hit the problem on the head before it gets any worse.

Dempsey is also intolerant of chicken - it isn't rare, but it isn't something you automatically think of!

glad he is on the mend
