Do you thinking raising my dogs water bowl will help?

i have an 8yr old carine terrie male. lately when he drinks water from a bowl located on the floor when he gets done he gags and somtimes some clear gunk comes out. i am pretty sure thats just spit he is otherwise a happy healthy little dog.i am just wondering if anyone else had this issue and if raising the bowl helped. when he goes for walks he does have a harness so he is not pulling on his throat thanks
