We have been made aware of the latest FDA report that outlines an on-going study of dilated cardiomyopathy (DCM) in dogs.  We are dog owners as well and wanted to make sure that our valued customers are made aware of the study along with getting accurate information from our food partners in order to alleviate any fears regarding their pets and their diet.  Below you will find information that outlines what DCM is, the nature of the studies performed, and the factual outcomes regarding the data that is available.  You can also find statements from our trusted food partners that discuss their response to the latest report.

What is DCM:


DCM is a disease of a dog’s heart muscle and results in an enlarged heart. As the heart and its chambers become dilated, it becomes harder for the heart to pump, and heart valves may

leak, which can lead to a buildup of fluids in the chest and abdomen (congestive heart failure). If caught early, heart function may improve in cases that are not linked to genetics with appropriate veterinary treatment and dietary modification.


How many cases have been reported to the FDA?


Between January 1, 2014 and April 30, 2018, the FDA received 524 case reports of diagnosed dilated cardiomyopathy. Some of these cases involved more than one animal from the same household. In the reported cases, there were 560 individual dogs diagnosed with DCM and 119 of those dogs died. There were 14 individual cats, 5 of which died. The agency received additional reports of cardiac symptoms in dogs, however, the reports did not include a confirmed DCM diagnosis.


What foods do we carry that are mentioned in the article?


Acana, Orijen, Taste of the Wild, NutriSource, Fromm.


Has the FDA asked any of these brands to recall?


The FDA has not yet determined the nature of the possible connection between these foods and canine DCM, so we do not have definitive information indicating that the food needs to be removed from the market.


Does the FDA know what it is about these foods that may be connected to canine DCM?


At this time, it is not clear what it is about these diets that may be connected to DCM in dogs. There are multiple possible causes of DCM. Taurine deficiency is well-documented as a potential cause of DCM, but it is not the only cause of DCM. Nutritional makeup of the main ingredients or how dogs process them, main ingredient sourcing, processing, amount used, or other factors could be involved.


Do I need to change my dog’s diet?


At this time, we are not advising dietary changes based solely on the information we have gathered so far. It’s important to note that the reports include dogs that have eaten grain-free and grain containing foods and also include vegetarian or vegan formulations. They also include all forms of diets: kibble, canned, raw and home-cooked. Therefore, we do not think these cases can be explained simply by whether or not they contain grains, or by brand or manufacturer.
