Bloat is the overstretching of the stomach due to excessive gas content, most commonly known as gastric dilatation-volvulus, gastric torsion and torsion. In dogs, excessive gas in stomach may cause twisting of the stomach locking the gas in. most breeds at risk are the deep-chested.

The immediate treatment is sphincter dysfunction between the stomach and esophagus as well as an outflow obstruction through the pylorus.

There are symptoms, which are not noticeable like any other kind of distress. A dog might stand with discomfort and uncomfortable without any obvious reasons. Other symptoms include hypersalivation, breathing constraints, depression, weakness and abdomen distension. A high percentage of dogs with bloat suffer from cardiac arrhythmias or abnormal electrical heart activity.
