Does elevating feeding dishes prevent canine bloat?

Question: 

There appears to be much disagreement among veterinarians regarding elevated feeding dishes to prevent canine bloat. What does recent research indicate?

Answer: 

There are many, many opinions and theories of the cause of bloat (Gastric Dilatation Volvulus, GDV) and/or prevention of this syndrome. None have demonstrated cause and effect. I know of no scientific studies regarding the efficacy of feeding in an elevated food dish for prevention of bloat. I would not rely on this procedure of feeding to prevent the accumulation of gas in the torsed stomach, they all call bloat.
