All I can think of is to massage his crop. Meanwhile don't give him any food or water, so he doesn't make it worse. Is there any way to have someone help hold him (or wrap him in a towel) to see if he has an obstruction in his mouth/throat?
Just a thought, but could he have water in his lungs (inhaled water accidentally or something)?
