Gastric Torsion

If this is the case your dog will try to vomit but will not produce anything. He/she will become rapidly uncomfortable and the left side of the abdomen starts to swell. THIS IS AN EMERGENCY WHICH SHOULD BE SEEN IMMEDIATELY.

You can prevent this in most cases by feeding large dogs more frequently during the day in smaller portions and by not having them play directly after feeding. Also excessive water intake after feeding can contribute to the problem.
