Recently, there have been reports of an increase in the number of cases of heart disease in dogs.
The FDA has alerted veterinary professionals of the potential for dilated cardiomyopathy in dogs eating certain pet foods.
These foods contain potatoes, peas, lentils or legumes as main ingredients. These ingredients are found most commonly in diets labeled as “grain-free.” The problem seems to be linked to a deficiency in the amino acid taurine.
Amino acids are considered the building blocks of the body. Some are made by the body utilizing other sources, but dogs have a very limited ability to synthesize taurine. It is considered an “essential amino acid” and needs to be available in the diet. Taurine is concentrated in the heart, retinas and brain. Taurine deficiency has long been associated with heart disease in cats, and since that discovery, it has been added to all cat foods. Here is what you need to know to provide the best care possible for your dog.
First, evaluate the diet you are feeding your dog. If potatoes, peas, legumes and/or lentils are in the ingredient list for the food you are using, contact your veterinarian to schedule an examination. A diet change or supplementation may be recommended. Bring the ingredient list of the food you are using to the appointment.
Watch for signs of heart disease. These include slowing down on walks, shortness of breath, weakness, coughing, trouble breathing or fainting. Schedule a visit with your veterinarian because abnormal heart rhythms or heart murmurs may be heard by your veterinarian during a physical examination. If these signs are noted, further diagnostics may be indicated.
If you find the suspect ingredients in your dog’s food and notice the symptoms of heart disease, speak with your veterinarian about testing for blood taurine levels and a diet change. Further testing and a taurine supplement may be indicated.
The FDA has asked veterinarians to share information with them to help to identify and address these issues. You may be asked permission to share information about your pet. We encourage you to allow this cooperation to help other pets experiencing these problems. If you have any questions, contact your veterinarian.
