I found a quote from Glickman, the man who ran the study,
here:
"Glickman presented some of the findings from his most recent "Five Year Purdue University Prospective Study of Gastric Dilatation-Volvulus" at Canine Health Conference held in St. Louis in October 1999 and sponsored by the AKC Canine Health Foundation. The purpose of the study was to isolate risk factors in order to identify the environmental situations and characteristics of dogs that make them more susceptible to the condition.
"We followed nearly 2000 dogs belonging to 11 breeds for up to five years to determine which one would develop bloat and which ones would not. Then, we related that data back to things like their breed, size, shape, personality, age, genetics, diet and how they were managed," he explains.The study was a two part risk analysis performed at the breed individual dog levels. At the conference, Glickman reported on the first part, the breed analysis findings, which are complete, but reported only the preliminary findings of the second part, the individual dog risk factors, which still are being analyzed at the time of this writing."
That bit highlighted in bold is what bothers me. Following large and giant breed dogs is not the same as running a controlled study. If 90% of the people that own a great dane feed it from a raised bowl then of course there will be more dogs that ate from raised bowls in the population that suffered from GDV. I'd really like to see a study where litters were split with half fed one way and half another - then let's see the results. If anyone has read the full paper I'd be really interested in knowing how the risk analysis was performed. (I suppose I should just buy it shouldn't I :))
