Gastric Dilation-Volvulus (GDV, Bloat)


This problem may occur when there is an abnormal accumulation of air, fluid and/or foam in the stomach, with or without “volvulus” (twisting) of the stomach and spleen.

This is a life threatening issue! 

If there is any reason to suspect bloat, please seek veterinary assistance for your pet immediately.

From the AKC Canine Health Foundation:

Bloat is of foremost concern to the AKC Canine Health Foundation and its donors, and as such will require a major research effort to identify the underlying mechanisms of this disease. In response to donor concern, we are launching a Bloat Research Initiative to better define, and ultimately eradicate, bloat in dogs.
