Effect of type of diet on blood and plasma taurine concentrations, cardiac biomarkers, and echocardiograms in 4 dog breeds
Journal of Veterinary Internal MedicineVolume 35, Issue 2 p. 771-779
This study of pure bred Whippet, Golden Retriever, Doberman Pinscher, or Miniature Schnauzer (~400 dogs) found some increases in cardiac blood markers in dogs fed grain free or diets with legumes, peas, or potatoes as key ingredients. But the association between cardiac issues and diet was inconclusive. The authors suggest that the correlation with diet is not clear because the causal ingredient(s) or nutrients have not been identified and many foods have shared ingredients making clear categorization of foods difficult (grain free vs those high in legumes, peas, potatoes).
