Summary:Background The United States Food and Drug Administration is investigating possible diet‐associated dilated cardiomyopathy (DCM) in dogs and cats. Objectives To retrospectively review DCM cases for signalment, diet information, echocardiographic changes, and survival. Animals Client‐owned dogs (n = 71). Methods Medical records of dogs diagnosed with DCM between January 1, 2014 and September 30, 2018 were reviewed. Dogs were grouped into “traditional” or “nontraditional” diet categories and whether or not diet was changed after diagnosis.
