Actually, Wendy, feeding a dry kibble DOES NOT increase the risk of bloat. But we got a chuckle at work tonight from your ‘statistic’ that it kills 1/3 of dogs.
Here’s some slightly more accurate info for anyone concerned.
In the bloated stomach, gas and/or food stretches the stomach many times its normal size, causing tremendous abdominal pain. For reasons we do not fully understand, this grossly distended stomach tends to rotate, thus twisting off not only its own blood supply but the only exit routes for the gas inside. Not only is this condition extremely painful but it is also rapidly life-threatening. A dog with a bloated, twisted stomach (more scientifically called gastric dilatation and volvulus) will die in pain in a matter of hours unless drastic steps are taken.
What are the Risk Factors for Developing Bloat?
Classically, this condition affects dog breeds that are said to be deep chested, meaning the length of their chest from backbone to sternum is relatively long while the chest width from right to left is narrow. Examples of deep chested breeds would be the Great Dane, Greyhound, and the setter breeds. Still, any dog can bloat, even dachshunds and Chihuahuas.
Dogs weighing more than 99 pounds have an approximate 20% risk of bloat.
Classically, before bloating the dog had eaten a large meal and exercised heavily shortly thereafter. Still, we usually do not know why a given dog bloats on an individual basis. No specific diet or dietary ingredient has been proven to be associated with bloat. Some factors found to increase and decrease the risk of bloat are listed below.
Factors Increasing the Risk of Bloat
Feeding only one meal a day
Having closely related family members with a history of bloat
Eating rapidly
Being thin or underweight
Moistening dry foods (particularly if citric acid is listed as a preservative)
Feeding from an elevated bowl
Restricting water before and after meals
Feeding a dry diet with animal fat listed in the first four ingredients
Fearful or anxious temperament
History of aggression towards people or other dogs
Male dogs are more likely to bloat than females
Older dogs (7 - 12 years) were the highest risk group
Factors Decreasing the Risk of Bloat
Inclusion of canned dog food in the diet
Inclusion of table scraps in the diet
Happy or easy-going temperament
Feeding a dry food containing a calcium-rich meat meal (such as meat/lamb meal, fish meal, chicken by-product meal, meat meal, or bone meal) listed in the first four ingredients of the ingredient list.
Eating two or more meals per day
Contrary to popular belief, cereal ingredients such as soy, wheat or corn in the first four ingredients of the ingredient list does not increase the risk of bloat.
In a study done by the Purdue University Research Group, headed by Dr. Lawrence T. Glickman, the Great Dane was the number one breed at risk for bloat, the St. Bernard was the #2 breed at risk, and the Weimaraner was the #3 breed at risk.
A study by Ward, Patonek, and Glickman reviewed the benefit of prophylactic surgery for bloat. Prophylactic surgery amounts to performing the gastropexy surgery (see below) in a healthy dog, usually in conjunction with spay or neuter. The lifetime risk of death from bloat was calculated, along with estimated treatment for bloat, versus cost of prophylactic gastropexy. Prophylactic gastropexy was found to make sense for at-risk breeds, especially the Great Dane, which is at highest risk for bloat.
