Gastric dilatation, commonly known as bloat, is a rapidly progressing and devastating condition that can develop in several different breeds of dogs. The condition is initiated when the stomach dilates and food and gas cannot be expelled. As the stomach dilates and expands, the pressure in the stomach begins to increase, causing inadequate blood return to the heart from the abdomen, loss of blood flow to the lining of the stomach, and rupture of the stomach wall. In some cases the stomach can become dilated enough to rotate in the abdomen, a condition called volvulus. The rotation can lead to blockage of the blood supply to the spleen and the stomach wall, and without immediate surgical correction of volvulus and removal of the dead tissues the patient can die.
Research funded through the Bloat Initiative aims to establish the causes and pre-dispositions for gastric dilatation-volvulus (GDV), or bloat.

CHF is excited to offer a free educational webinar "Bloat: What Every Dog Owner Needs to Know" with Dr. Elizabeth Rozanski. In the webinar, Dr. Rozanski explains what every dog owner needs to know about gastric dilatation-volvulus, or bloat. She presents the signs and treatment options for bloat along with current options for prevention.
The Foundation also plans to provide continuing education for veterinarians showing surgical procedures used for prevention - gastropexy during spay/neuter.
