In Italian Forum we usually speak a lot about Gastric contortion, and I can say, by reading, as I am no owner yet - one day I'll be I hope
- that CSVs can have it too. So the advices that are usually given are these:
1 - Divide the daily food income in two meals - so that the stomach does not get too full
2 - Keep the dog quiet for AT LEAST one hour before eating and AT LEAST two hours after eating
3 - If dogfood is used, avoid a great income of water immediately after the meal. Give just a small amount, and then more after few time.
4 - Check if the dog "burps". It is a good sign: the gas exits from the stomach and the way is free
5 - Do not water the dogfood: it absorbs water and starts creating gas in the stomach (same reason as per Point 3).
That's all I can remember right now ^^...
