i dunno, i'd be worried. stress can bring on both bloat and torsion, and the symptoms aren't always the same. the eating grass and vomiting worries me too. i truly think a vet visit is in order.
ps...please re-think the "stubborn" issue, dogs do not have that human emotion. dogs operate primarily upon instinct. no stubborn or getting even or vindictive in the dog brain.
again, i'd be real concerned. hope i'm overreacting and that it's just an upset tummy from stress.
