Grain-free diets are dog foods that do not contain grains, such as wheat, corn, or rice.
There is some concern that grain-free diets may be linked to a type of heart disease called dilated cardiomyopathy (DCM).
One possible explanation for the link between grain-free diets and DCM is taurine deficiency.
The FDA is currently investigating the link between grain-free diets and DCM.
If you feed your dog a grain-free diet, it is important to talk to your veterinarian.
In addition to the risk of DCM, grain-free diets may also be linked to other health problems, such as kidney disease and skin problems.
