Hi Chloe
I have Wolfhounds and I always feed them from a raised platform. It doesn't have to be very high, my bitch has 2 concrete blocks, one on top the other, so it is probably about 9 inches high.
However, I know that this is now considered *old fashioned* and there has been conflicting opinions on this subject recently.

I have read that some studies show that raising the bowl "increases" the chances of bloat (study was American I think). (It's a bit like which way to put a baby in a cot, on their front or on their back, the recommendations change :rolleyes: ).
Personally, I feel that a bowl raised from the ground is a good idea in lots of ways. e.g. It stops giant/large dogs having to splay their front legs to eat, the food goes down with gravity not against it, etc. :)
I think anything you can do to reduce the risk of Torsion is worth doing. Feed twice a day for life, raise the bowl, no exersize before or after feeding, etc.
JMHO, I hope it helps you to decide. :D
