Bloat and Gastric Torsion in Large Breed Dogs
Bloat, also known as Gastric Dilatation-Volvulus (GDV) is a serious condition that can happen to any large breed dog.
Bloat (dilation) is a condition of an abnormal accumulation of air, fluid, and/or foam in the stomach and can occur with our without the twisting (volvulus) of the stomach. When the stomach twists, the passageways become blocked and trap gases and contents inside the stomach. This silent killer is the second leading cause of death in dogs behind cancer.
Who is at risk?
Large dogs with deep chests are prone to this condition, for example but not limited to: Great Danes, Dobermans, and German Shepherds. Males, older dogs, and those that are particularly large for their breed have a greater risk. Dogs with bloat in their hereditary background also face a higher risk of the condition. While it can occur at any age, it typically occurs in middle-aged and older dogs.
Rapid eating followed by exercise is the main cause of bloat, however it can also be caused by stress and anxiety. Drinking lots of water before or after eating as well as eating very fatty foods can also cause the stomach to bloat.
A dog with a bloated stomach will have a chest that feels very tight to the touch. They will act uncomfortable, restless and anxious and may also have foamy saliva along with attempts to vomit. Other symptoms include lethargy, coughing, gagging, pacing, whining, and shallow breathing.
Dogs with this volvulus are unable to belch or vomit and will ultimately experience other complications such as dehydration, circulatory shock, gastric perforation, bacterial septicemia, and death.
When bloat is suspected, the dog should be rushed to the veterinary clinic immediately. Dilation is treated by inserting a long tube through the dog's mouth to relieve the pressure in the stomach. If the dog has volvulus, treatment requires timely surgery to correct the situation. Untreated pets will typically pass away within less than 24 hours. The cost of surgery is around $2,000-$6,000.
Bloat can easily be prevented when the pet owner is knowledgeable and prepared. To prevent this condition, meals should be fed multiple times per day, rather than one large meal. Feed low-fat meals, do not use raised food bowls, and do not allow rapid eating. Most importantly, be sure that the dog waits at least an hour after eating before exercising or getting into stressful situations.
