A. No, elevated food and water do not necessarily prevent bloat, but actually can increase the risk of it.
There is no definitive defined cause for bloat, but there are some recognized risk factors such as having one large meal a day (feed 2-3 meals during the day rather than one large meal), eating quickly, exercise and running or playing after eating (Wait at least one hour after eating or drinking before allowing exercise), eating or drinking too much, stress.
I would suggest to take these precautions to help prevent this condition.
A. It's not likely to make a huge difference, it's more important to follow some guidelines that could prevent GDV instead:
Don't feed your dog before or after long walks or exercise, restrict large water consumption after a large meal, don't encourage your dog to jump - especially after food.
If you are planning to spay her soon, you should consider opting for a gastropexy procedure. This simple procedure can be done on the same occasion the day she is spayed and involves attaching the stomach to the body wall which prevents GDV from happening.
