Excerpt:
Based on the information gathered as part of our investigation to date, our advice to pet owners remains consistent. The agency has not identified specific recommendations about diet changes for dogs who are not displaying DCM symptoms, but encourages pet owners to consult directly with their veterinarians for their animal’s dietary advice. FDA-CVM investigative activities include:
Analyzing cases statistically to search for correlations between diagnosed DCM cases and what those dogs did or did not eat.
Working with the Veterinary Laboratory Investigation and Response Network (Vet-LIRN), a collaboration of government and veterinary diagnostic laboratories to test blood, serum and tissues from affected animals.
Collaborating with Chesapeake Veterinary Cardiology Associates (CVCA) to collect case summaries and blood/serum/tissue of dogs diagnosed with DCM to see if there are unique factors that separate diet-associated DCM from genetic. The FDA is also reviewing echocardiograms of dogs who are not showing symptoms of DCM to evaluate the significance of early changes in heart function.
Consulting with board certified veterinarians in animal nutrition to identify nutritional factors such as nutrient bioavailability and ingredient digestibility that may contribute to the development of heart disease.
Examining ingredient sourcing/processing and product formulation with pet food manufacturers.
