Ok maybe you need to start from square 1 again.. But since he has tummy trouble I would try L.I.D food from Natural Balance... It has one simple protien and 1 simple carb.. grain free... they even have it in wet food too.. try i kind they he has never had... maybe like the one with Sweet potato & Bison or the Sweet potato and Venison... Don't give any treats.. just offer him food... sooner or later he will eat it
