![]() However, it can still be seen in cats eating home-prepared diets or commercial diets prepared with inadequate nutritional expertise or quality control. On the basis of that report and substantial subsequent research, the requirement for taurine in cat foods was increased, and taurine deficiency–related DCM is now uncommon in cats. In 1987, however, Pion et al 1 published a landmark paper reporting that DCM in cats was associated with taurine deficiency and could be reversed by providing supplemental taurine. ![]() Therefore, we wanted to increase awareness of this issue among veterinarians, review what is currently known about the possible association between certain diets and DCM in dogs, and discuss what veterinarians can do to help identify underlying causes.Äilated cardiomyopathy used to be one of the most common cardiac diseases in cats. The recent announcement from the US FDA 3 alerting pet owners and veterinarians about reports of DCM in dogs eating pet foods containing peas, lentils, other legume seeds, or potatoes as main ingredients has raised concerns among the pet-owning public. Further, possible diet-associated DCM represented 16% of all cases of DCM diagnosed by the respondents during this period. Dogs for which breed was specified consisted of mixed-breed dogs (n = 134), Golden Retrievers (23), Labrador Retrievers (9), German Shepherd Dogs (8), Cocker Spaniels (7), and between 1 and 5 dogs each of 25 other breeds. However, when one of the authors (RF) recently surveyed veterinary cardiologists about cases of possible diet-associated DCM in dogs examined in the past 2 years, information for > 240 cases was obtained, with responses received from the United States, United Kingdom, Canada, Israel, and Austria (unpublished data). The extent of this issue is not clear, not all cases have been confirmed to be linked to diet, and a true association has not been proven to exist. 2 The association between diet and DCM in dogs has generally not been much in the news since the early 2000s, but over the past few years, an increasing number of DCM cases involving dogs appear to have been related to diet. Diet-associated DCM first came to light in cats in the late 1980s 1 and in dogs in the mid-1990s.
