The following study, published in the journal Translational Animal Science, determined the effects of feeding a commercial grain-free diet to large breed dogs on taurine status and overall health.

While there is a known relationship between low taurine status and DCM, there are few studies published to evaluate the relationship of commercial grain-free diets and taurine status in healthy large-breed dogs. In some FDA case reports, dogs diagnosed with DCM consuming grain-free diets also had low concentrations of plasma or whole blood taurine. Brief: In 2018, the United States Food and Drug Administration (FDA) released a statement that grain-free diets may be related to the development of canine dilated cardiomyopathy (DCM).
