Both V-dog Crunchy Nuggets and V-dog Traditonal Flakes contain a supplement called L-Carnitine, but what does it do?
Dogs are able to naturally synthesize Carnitine and that's true of most if not all mammals, however some recent studies have shown the biosynthesis of Carnitine may be insufficient in certain animals.
Despite there being no requirement for Carnitine, at the time of writing this, in either the Nutritional Research Council (NRC) guidelines or the FEDIAF (European Pet Food Industry) guidelines, Carnitine supplementation has been observed to be beneficial in the treatment of dilated cardiomyopathy in certain families of dogs.
Dilated cardiomyopathy (DCM) is a disease of the heart muscle, where typically the enlarged heart does not function properly. Left untreated this can lead to congestive heart failure (CHF).
Depending on what report or website you read, DCM can effect Doberman Pinschers, Great Danes, Boxers, and Cocker Spaniels.
If in any doubt please check with your Vet.
