The health and wellbeing of our canine companions are of utmost importance to dog owners worldwide. One significant threat to their health is heart disease, a condition that can be triggered or exacerbated by the food they eat. Recent studies and investigations by veterinary and regulatory bodies have shed light on certain dog foods that may be associated with an increased risk of heart disease in dogs. This article aims to delve into the specifics of this critical issue, exploring the dog foods linked to heart disease and what pet owners can do to keep their pets safe and healthy.
Introduction to Heart Disease in Dogs
Heart disease in dogs, also known as canine dilated cardiomyopathy (DCM), is a condition where the heart muscle becomes weak and cannot pump blood efficiently. This can lead to an accumulation of fluid in the lungs, chest, or abdomen, and if untreated, can result in heart failure. While heart disease can be genetic, recent research has highlighted a potential link between diet, specifically certain ingredients in dog food, and the development of DCM in dogs.
The Role of Diet in Canine Heart Disease
The investigation into the dietary causes of heart disease in dogs has centered around foods containing peas, lentils, chickpeas, and potatoes as main ingredients. These foods, often marketed as “grain-free,” have become popular over the last decade due to the misconception that grains are harmful to dogs. However, grains are actually a good source of nutrients, and their removal from dog food can lead to nutritional deficiencies if not properly replaced.
Nutritional Deficiencies and Heart Disease
A key nutrient that has been implicated in the development of heart disease in dogs is taurine, an amino acid essential for heart health. Some studies suggest that the high levels of legumes in grain-free diets may interfere with taurine absorption, potentially leading to a deficiency and increasing the risk of DCM. Additionally, the lack of L-carnitine and other B vitamins in these diets could also play a role in the development of heart disease.
Identifying the Dog Foods Linked to Heart Disease
Based on reports to the FDA and veterinary research, several dog food brands have been identified as potentially increasing the risk of heart disease in canines. While it’s essential to note that not all dogs eating these foods will develop heart disease, and many factors contribute to an individual dog’s risk, being informed about these brands can help pet owners make better choices for their pets. The 16 dog foods that have been linked to heart disease include:
- Acana

Understanding the Risks and What You Can Do
If your dog is currently eating one of the mentioned foods, it’s crucial not to panic. The risk of heart disease varies based on several factors, including the specific formulation of the food, the length of time your dog has been eating it, and your dog’s individual health status and breed predisposition. Regular veterinary check-ups can help in early detection of heart disease, and switching to a well-balanced, nutrient-rich dog food may mitigate some risks.
Choosing the Right Dog Food
Selecting the best dog food for your pet involves considering several factors, including nutritional content, ingredient quality, and your dog’s life stage, size, and health conditions. Opting for dog foods that are rich in taurine and L-carnitine, and choosing brands that conduct rigorous nutritional research and testing, can be beneficial. Additionally, consulting with your veterinarian to determine the most appropriate diet for your dog can provide personalized advice tailored to your pet’s unique needs.
