Years ago, when I was in Danes, if one suspected bloat, we all said "get a bottle of pepto down them", then get to the vet.
Anyone who suspects bloat, should get to the vet asap. Many times you have less than 2 hours if they are in torsion. You cannot "cure" bloat with GasX or pepto. You can possiblyy slow down the gas production which will buy you time to get to the vet!
