Bloat – Gastric Dilation-Volvulus (GDV)
This is an extremely serious first aid situation. It occurs when the stomach becomes enlarged through a build-up of gas and then twists along its long axis. Gas then continues to build up because both entry and exit points in the stomach are blocked. This usually causes a very sudden, rapid onset of clinical signs.
GDV principally affects large breed, deep-chested dogs. For example: Irish Wolfhounds, Spinones, Chow Chows, Irish Setters etc. However any dog, including the Labrador can be affected. In fact, Robbie, my black Lab is prone to eating rapidly. Before I got him a Go Slower bowl we had an incident that caused him to get a very gasy tum. Had I not been able to recognise the signs, things may have turned out very differently!
