Dogs Fed Some Trendy Diets Could Be at Risk of Heart Disease:
January 29, 2019
University of California, Davis, veterinarians led a team that has found a link between some popular grain-free, legume-rich dog diets and a type of nutritional deficiency and canine heart disease known as taurine-deficient dilated cardiomyopathy. The study was recently published in the journal PLOS ONE.
Researchers found dogs eating some of these boutique diets are not making or maintaining enough taurine, an amino acid important for heart health. Taurine deficiency has been known for many years to lead to dilated cardiomyopathy, or DCM, a heart muscle disorder that can lead to congestive heart failure and death.
“Given this recent surge in cases, we need to pay close attention to what we are feeding dogs,” said lead author Joshua Stern, a veterinary cardiologist and geneticist at the UC Davis School of Veterinary Medicine. “Choosing a well-researched dog food that has a healthy nutrient profile backed by expert formulation and research is of paramount importance.”
Stern said while some dog breeds are more genetically prone to a traditional form of DCM, the disease is now showing up unexpectedly in other breeds, such as the golden retriever. The common link unifying these cases is their diets. He began noticing the trend two years ago and is now treating many dogs with nutritionally mediated DCM that were all eating quite similar diets. Last year, the U.S. Food and Drug Administration issued an alert to pet owners and veterinarians about the potential association between the diets and DCM. The FDA continues to research this issue in an effort to help identify the exact dietary factor causing the problem.
