I've had three dogs have torsions , one "bloat" , and two intestinal torsions ..... as you see in the vids a stomach torsion is evident right away , intestinal torsion not so much ........... all three dogs were middle aged edgy males , I think temperament had a lot to do with it ........ I personally never have given a thought about preventing it , even after having it happen , i'm of the opinion if it's going to happen it'll happen ..... the stomach torsion was in the morning easily more than 12hrs after eating . one of the intestinal torsions I believe was from the male breeding .......... I do believe it is genetic in that body type and temperament are genetic .... the body type that predisposes them to it is the body type I/we look for , the temperament is common , but not something folks are looking for , at least not me .............
