In today's VETgirl online veterinary continuing education podcast, we review whether or not echocardiographic phenotype of canine dilated cardiomyopathy differs based on canine diet types.

DCM in association with taurine and L-carnitine deficiency is well documented and has the potential for reversal of myocardial dysfunction with appropriate supplementation.
