DCM & Grain Free Diets

11 Jul 2019

You may be aware of media outlets discussing potential issues surrounding Grain Free dog food and specifically Dilated Cardiomyopathy (DCM)

As valued customers we would like to ensure we provide you with as much information as possible to alleviate any concerns and ensure you are provided with the correct facts, figures and published research.


Since the initial alert issued by the United States Food & Drug Administration(FDA) in July 2018 regarding an increase in the number of cases of atypical DCM in dogs in the USA, very little progress has seemingly been made into understanding the cause.

The latest 'information' released by the FDA (27th June 2019) merely provided limited details and statistics regarding the dogs and cats that have been affected as well as the types of diet they have been fed, what brands of food have been fed and what ingredients they contain.

Based on data released by the FDA diets characteristics as grain-free were fed in 91% of the DCM cases reported.

Unfortunately, data such as this has generated some attention grabbing headlines and stories in various news and social media outlets. However, the fact is that the FDA have not found any specific causative link between and particular brand or type of diet (e.g. grain-free) or ingredient (e.g. peas, lentils, sweet potatoes) and DCM


Facts and Figures

Given that and estimated 22 Million dogs in the USA are fed on a grain food and grain-free foods have been available for 10 years or more with no problems reported, the number of dogs affected in the last year (560) is a tiny fraction (0.002%) and suggests that there is not a general problem with grain-free diets themselves. Furthermore, there is no similar issue in the UK or Europe, where the grain free diets are also widely consumed by dogs and cats.

Causes Unknown

The cause(s) for the increase in cases of atypical DCM remains unknown

The FDA is continuing its investigation, working with scientists and nutritionist in the veterinary Laboratory and Investigation Response Network (Vet-LIRN), and also with veterinary cardiologists.
