Abstract
<p><strong><span lang="EN-US">Clinical bottom line:</span></strong></p><p><span lang="EN-US"><span>Most of the studies that attempt to either partially or fully address the PICO contain limitations that mean that they should either be rejected as unable to address the PICO or viewed with caution due to potential bias in the population studied. Of the two studies that remain, the findings conflict. One study found dogs fed a diet containing small particles only (&lt;5mm, mainly dry kibble fed dogs) at greater risk of GDV than those fed a diet containing large particles (&gt;30mm, at least partly non-kibble based). The other study found no significant effect of kibble on GDV risk once other potential risk factors were controlled for in the analysis. Consequently, there is insufficient quality evidence to support the claim that feeding a kibble diet is associated with an increased risk of GDV. However, it is worth noting that no studies found that dogs fed a diet that contained no kibble (dry or moistened) were at increased risk of GDV, and the addition of either table scraps, canned food or non-kibble supplements to the dog’s diet reduced the risk in some studies but more research is needed to unpack the implications of this for feeding a kibble diet.</span></span></p><br /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/oa-icon.jpg" alt="Open Access" /> <img src="https://www.veterinaryevidence.org/rcvskmod/icons/pr-icon.jpg" alt="Peer Reviewed" />
Highlights
Sample size: 2551 surveys included in the analysis: Control group: 1437 respondents Gastric dilatation-volvulus group (GDV): 1114 respondents
Control group: The same questions were asked of the control group dog owners as were asked of the GDV group, with the exception that they were not asked any questions about the GDV episode
Main findings:: Dogs fed a diet that contained some particles that were greater than 30mm were 75% less likely to have a GDV episode than dogs fed a diet in which the maximum particle size was
Summary
Population: Privately owned dogs (any breed or mix, both sexes, neutered and entire) across a wide geographic area. The survey was potentially available to English speaking dog owners with access to the internet in any country worldwide. Sample size: 2551 surveys included in the analysis: Control group (dogs without a GDV): 1437 respondents Gastric dilatation-volvulus group (GDV): 1114 respondents. Intervention details: Online survey based study, with ad hoc convenience sampling of dog owners. Demographic information (year of birth, breed, sex, neuter status, and purpose of the dog; country and postcode of respondent). Whether the dog had ever had a GDV that required surgical intervention. This latter question was used to divide dogs into the control group and the GDV group. 2. GDV group: a series of 44 questions divided into 4 categories were asked that covered: i.
