Legumes, including pulse ingredients, have been used in pet foods for many years, with no evidence to indicate they are inherently dangerous, but analysis of data reported to the <a href="/wiki/Center_for_Veterinary_Medicine" title="Center for Veterinary Medicine">Center for Veterinary Medicine</a> indicates that pulse ingredients are used in many "grain-free" diets in greater proportion than in most grain-containing formulas. FDA has asked pet food manufacturers to provide diet formulations so we can further understand the proportions of ingredients in commercially-available diets and possible relationships with non-hereditary DCM. The FDA does not know the specific connection between these diets and cases of non-hereditary DCM and is continuing to explore the role of genetics, underlying medical conditions, and/or other factors.<sup id="cite_ref-fdacau_93-0" class="reference"><a href="#cite_note-fdacau-93"><span class="cite-bracket">&#91;</span>93<span class="cite-bracket">&#93;</span></a></sup></p></blockquote> <div class="mw-heading mw-heading3"><h3 id="Vegetarian_and_vegan">Vegetarian and vegan</h3></div> <link rel="mw-deduplicated-inline-style" href="mw-data:TemplateStyles:r1236090951"><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Vegetarian_and_vegan_dog_diet" title="Vegetarian and vegan dog diet">Vegetarian and vegan dog diet</a></div> <p>Like the <a href="/wiki/Human" title="Human">human</a> practice of <a href="/wiki/Veganism" title="Veganism">veganism</a>, vegan dog foods are those formulated with the exclusion of <a href="/wiki/Ingredient" title="Ingredient">ingredients</a> that contain or were processed with any part of an <a href="/wiki/Animal" title="Animal">animal</a>, or any <a href="/wiki/Animal_product" title="Animal product">animal byproduct</a>.<sup id="cite_ref-94" class="reference"><a href="#cite_note-94"><span class="cite-bracket">&#91;</span>94<span class="cite-bracket">&#93;</span></a></sup> A 2023 systematic review found no evidence of serious impacts on animal health from vegetarian cat and dog diets; however, the authors noted that the studies suffered from issues such as selection bias, low sample size, and short feeding periods and recommended further research.<sup id="cite_ref-10.3390/vetsci10010052_95-0" class="reference"><a href="#cite_note-10.3390/vetsci10010052-95"><span class="cite-bracket">&#91;</span>95<span class="cite-bracket">&#93;</span></a></sup> The <a href="/wiki/Omnivore" title="Omnivore">omnivorous</a> <a href="/wiki/Dog" title="Dog">domestic canine</a> has evolved to metabolize <a href="/wiki/Carbohydrate" title="Carbohydrate">carbohydrates</a> and thrive on a diet lower in <a href="/wiki/Protein" title="Protein">protein</a>, and a vegan diet may be adequate if properly formulated and balanced.<sup id="cite_ref-:9_96-0" class="reference"><a href="#cite_note-:9-96"><span class="cite-bracket">&#91;</span>96<span class="cite-bracket">&#93;</span></a></sup><sup class="noprint Inline-Template noprint noexcerpt Template-Fact" style="white-space:nowrap;">&#91;<i><a href="/wiki/Wikipedia:NOTRS" class="mw-redirect" title="Wikipedia:NOTRS"><span title="This claim needs references to better sources.
