I just got this from a friend - has anyone seen this? I do not know when it
came out, please pardon if this is a repeat from another source.

NEW Purdue Bloat Study
Recent studies are shedding more light on gastric dilatation volvulus (GDV),
otherwise known as bloat. GDVis the second leading cause of death in
large-breed (50 - 99 pounds) and giant-breed (100 pounds and over)
dogs.Approximately one in four large-breed dogs and one in five giant-breed
dogs may develop GDV during their lifetime,with some breeds at even higher
lifetime risk. GDV strikes suddenly and has a mortality rate as high as 30
percent.
In GDV there is a rapid accumulation of air in the stomach, causing distention
and often rotation of the stomach,cutting off blood supply at both ends and
causing the dog to go into shock. GDV is an acute emergency and rushingthe dog
to immediate veterinary care is essential. The risk of a dog developing GDV
increases with age. Otherfactors that increase a dog´s risk are having a
first-generation relative with a history of GDV, having a deep andnarrow chest
or abdomen, being thin, experiencing a major health problem before age 1, and
having a fearful ornervous temperament.
Research primarily at Purdue University by Dr. Larry Glickman, VMD, Ph.D, (an
AKC Excellence in CanineResearch Award winner), and Dr. Malathi Raghavan, DVM,
Ph.D. has identified a number of feeding managementand dietary factors that
increase the risk of GDV. These include eating only one meal a day, feeding
only dry dogfood, feeding food with only small particles, and feeding a large
volume of food per meal. Other feeding factors foundto increase the risk of GDV
were eating rapidly, increased physical activity before and eating, restricting
a dogswater intake before and after eating, moistening dry food before feeding,
and eating from a raised feeding bowl. Thus,some of the recommendations
commonly made to prevent GDV were shown by the research to actually increase
the risk of GDV. In the Journal of the American Veterinary Medical Association,
Vol. 17, No. 10, Glickman wrote, "Inaddition, in univariate analysises, many of
the recommendations commonly made to prevent GDV, such as raisingthe food bowl,
moistening dry food prior to feeding, and restricting water intake before and
after feeding, wereassociated with a significantly increased risk of GDV."
Recent research, not yet published, has shown an increased risk of GDV in dogs
who consumed dry foodscontaining fat among the first four ingredients, and an
increased risk in dogs who consumed dry foods listing citricacid as a
preservative - with this risk rising when foods with citric acid were
moistened. Although not statisticallysignificant, researchers found that a
modest increase in risk of GDV was seen with the consumption of dry foodsthat
listed more than one corn ingredient among the first four label ingredients,
while in contrast, a pattern wasobserved of decreased GDV risk with an
increasing number of protein ingredients of animal origin, including
beef,poultry, lamb, and fish among the first four ingredients.
STUDY RECOMMENDATIONS
* Feed twoor more meals a day
* Feed no more than one cup per 33 pounds of body weight per meal when feeding
two meals a day
* Feed an energy-dense diet, to reduce volume, but avoid a diet where a high
amount of calories are from fats.
* Feed a variety of different food types regularly. The inclusion of human
foods in a primarily dry dog food diet was
associated with a 59 percent decreased risk of GDV while inclusion of canned
pet foods was associated with a 28
percent decreased risk
* When feeding dry food, also include foods with sufficient amounts of meats
and meat meals, for example: beef,
lamb, poultry, and fish.
* Feed a food with larger particles, and include larger pieces of meat to the
diet.
* Avoid moistening dry foods
* If your dog eats rapidly, find ways to try to reduce his speed of eating
* Avoid raising the food bowl - place it at ground level
* Try to minimize stress for your dog. Stressful events have been reported to
be precipitating factors in GDV
occurrence.
* Restrict vigorous exercise one hour before and two hours after meals.
* When you are not in close proximity to your dog, use a baby monitor to alert
you if your dog is in distress.
* Learn to recognize signs of GDV, which include pacing and restlessness, head
turning to look at the abdomen,
distention of the abdomen, rapid shallow breathing, nonproductive attempts at
vomiting, and salivation. These
symptoms can progress rapidly to shock and death. Get to your veterinarian or
emergency hospital the moment you
suspect GDV
