If the joints are apart I sand them and also use a drill bit to remove old dowels or parts of them, so I can re-use those holes. I re-glue everything with 'Chair Doctor' glue and new dowels that have ridges and are slightly larger than original.
Elmer's glue or any other good white glue.
If the glue was a good glue then you will damage the wood before the glue lets go. Glue goes into the pores of the wood and holds tight. Usually to separate the two pieces you would need to saw them apart. This would give you a smoother separation.
Any wood glue, Elmer's white glue, TiteBond or many others will glue two boards.
