In July 2018, the FDA started investigating boutique, grain-free diets that have a potential link to dilated cardiomyopathy (DCM) in dogs. The diets in question contain pea, legume seeds, lentils, and/or potatoes as part of their main ingredients. Multiple factors may be involved in this potential link to DCM.
DCM is a very serious irreversible heart condition with a high mortality rate that is usually associated with large and giant breed dogs (Doberman Pinscher, Irish Wolfhound, or Great Dane). Because an unusually high incidence of DCM in other breeds is being seen, grain-free diets have been determined to have something to do with it.
Research is currently being done to further understand this association, but in the meantime if you are using a grain-free diet, we highly recommend gradually transitioning your dog to a non-grain-free diet.
If you notice signs of DCM such as exercise intolerance, collapse, cough, and/or difficulty with breathing, contact us immediately or go to an emergency clinic after hours if needed.
If you have any questions or concerns, we are always just a phonecall away!
