Risks Of Sweet Potatoes For Dogs
Risk Of Canine Dilated Cardiomyopathy (DCM)
DCM is a common heart condition in dogs. It is when there is not enough pressure to pump the blood around the body. While DCM is not uncommon in dogs, it is more common in certain breeds. These are usually larger breeds, including Afghan Hounds, Saint Bernards, Newfoundlands, Great Danes, Irish Wolfhounds, etc.
Breeds not generally at high risk of DCM were being reported of suffering with it. The FDA is investigating a possible link between dogs who consumed a diet primarily made up of potatoes and legumes (including lentils, chickpeas, pulses, and other peas and beans) and acquiring DCM.
The FDA is still exploring this. Check this for more information and to keep up to date.
