Burns, editor-in-chief of <em>Today\u2019s Veterinary Nurse<\/em> and author of an article examining the relationship between grain-free diets and dilated cardiomyopathy that will be published in the Winter 2020 issue of <em>TVN<\/em>. \u201cOften seen in DCM cases are abnormal heart rhythms, congestive heart failure, and sometimes even sudden death,\u201d Burns reports.<\/p>\n<p>In the past couple of years, veterinary cardiologists have been reporting increased rates of DCM in dogs \u2013 in the breeds with a genetic predisposition for DCM (typically large and giant breeds \u2014 Doberman Pinscher, boxer, Irish wolfhound, and Great Dane \u2014 and cocker spaniels), as well as in small dog breeds not usually connected with DCM. It\u2019s been theorized that in dogs with no genetic predisposition for DCM, the disease might be caused by the dogs eating boutique or grain-free diets. \u201cWhat has also been documented,\u201d says Burns, \u201cis that both the typical and atypical breeds were more likely to be eating boutique or grain-free diets, and diets with exotic ingredients \u2013 kangaroo, lentils, duck, pea, fava bean, tapioca, salmon, lamb, barley, bison, venison, and chickpeas. This is further associated when improvement in the dogs\u2019 condition is seen upon diet change.\u201d<\/p>\n<p>Further muddying the waters is whether the lack of amino acid taurine in grain-free pet foods plays a role; as of now, it is unclear whether taurine deficiency is a cause of DCM. In fact, many of the affected dogs have normal taurine levels, and giving taurine is unlikely to prevent DCM unless the dog has taurine deficiency.<\/p>\n<p>What\u2019s worse, says Burns, pet owners \u201care often getting their information from non-veterinary personnel or from the internet.\u201d Burns emphasizes: \u201cTo date, no credible evidence has been found showing grain-free diets are better for pets, nor do any nutritional foundations support this claim.\u201d<\/p>\n<h3>The Research Continues<\/h3>\n<p>To date, the U.S. Food and Drug Administration (FDA) Center for Veterinary Medicine has not established why certain diets may be associated with the development of DCM in dogs not predisposed to DCM. The FDA, veterinary nutritionists and veterinary cardiologists are continuing the research.<\/p>\n<p>It can be difficult to create a sophisticated poll on Facebook \u2014 questions must be designed so that respondents can \u201cvote\u201d with a \u201cyes\u201d or \u201cno\u201d response \u2014 and this is a complex issue. Some pet owners and veterinary professionals are unaware of the FDA research or completely doubt it; some think DCM is caused only by grain-free diets; some think it\u2019s only related to taurine deficiency. To understand the level of understanding of our Facebook fans and readers \u2014 and to help dispel some misunderstandings related to DCM and grain-free diets \u2014 we created a poll that asked: Do you understand the relationship between grain-free diets and dilated cardiomyopathy? Nearly 600 people took the poll; 69% answered \u201cyes\u201d; 31% responded \u201cno.\u201d<\/p>\n<hr \/>\n<p>https:\/\/www.facebook.com\/todaysveterinarynurse\/posts\/2330804186955325?__tn__=-R<\/p>\n<p>&nbsp;<\/p>\n<hr \/>\n<p>One respondent who answered \u201cyes\u201d makes this excellent point: \u201cIt may be difficult to answer this question as there is a relationship to some grain-free diets and some dogs getting DCM but not all grain-free (Purina Derm naturals has no cases and a different ingredient profile list that is seen in listed diets). Researchers are still investigating the exact cause. It might be better to ask, \u2018Do you understand the concerns with those diets listed as grain-free, with limited number, and rare sources of ingredients, and DCM?\u2019\u201d<\/p>\n<p>Another respondent correctly points out that we do not yet know what is causing this disease in DCM in some dogs: \u201cThat\u2019s a loaded question because no one does. That&#8217;s why the study is ongoing.\u201d<\/p>\n<h3>Stay Updated<\/h3>\n<p>The FDA recently issued <a href=\"https:\/\/www.fda.gov\/animal-veterinary\/cvm-updates\/fda-provides-third-status-report-investigation-potential-connection-between-certain-diets-and-cases?utm_campaign=6-27-2019%20DCM%20Update&amp;utm_medium=email&amp;utm_source=Eloqua\">an update<\/a> to its investigation into the potential connection between certain diets and DCM in dogs. (While the FDA has received reports of cats with DCM, the low number of reports \u2014 only 10 since January 2014 \u2014 has led the FDA to focus on cases in dogs only.) As Burns details in her article, the agency is particularly targeting diets that list peas, lentils, other legume seeds and potatoes within the first 10 ingredients on the label.<\/p>\n<p>Burns concludes her article by noting that \u201cthe growing grain-free category of the expanding pet food market is perpetuating the misperception that grain is bad for pets.\u201d<\/p>\n<p>Still, misperceptions and confusion persist. As one respondent said: \u201cPersonally, I need a hell of a lot more evidence before I 100% believe this. I am not saying it isn\u2019t possible and shouldn\u2019t be explored, but right now, I am not 100% convinced.\u201d<\/p>\n<h3>Learn More<\/h3>\n<p>Visit the <a href=\"https:\/\/todaysveterinarynurse.com\/clinical_topics\/nutrition\/\">Nutrition Archives<\/a> of <em>Today\u2019s Veterinary Nurse<\/em>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>There has been a lot of confusion, misinformation and conversation in the past year about the risk of heart disease in dogs due to being fed grain-free diets.<\/p>\n","protected":false},"author":1,"featured_media":4306,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"iawp_total_views":0,"footnotes":""},"categories":[211],"tags":[],"class_list":["post-4302","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-digital-exclusive","clinical_topics-cardiology","clinical_topics-news","clinical_topics-nutrition"],"acf":{"hide_sidebar":false,"hide_sidebar_ad":false,"hide_all_ads":false},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v24.7 (Yoast SEO v27.4) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>Poll: Grain-Free Diets and Dilated Cardiomyopathy | Today&#039;s Veterinary Nurse<\/title>\n<meta name=\"description\" content=\"There\u2019s been a lot of confusion and misinformation about the risk of heart disease in dogs being fed grain-free diets.
