Recent research has concluded that many Grain-free diets have been linked to heart disease later in dog's lives. The disease is called Dilated Cardiomyopathy (DCM). Symptoms include: tiring easily, coughing, trouble breathing, sudden weakness, and collapse. This is caused by an enlarged, weak heart that cannot pump blood efficiently.

Below we have a graph of the companies whose Grain-Free diets have caused the most cases. We suggest that if you are feeding any of these diets, please stop immediately.
