The size of the dog will determine the proper dosage. While L-carnitine supplements may improve this deficiency, keep in mind that many dogs will not show improvement. In addition, some dogs will show an increase in diarrhea as the carnitine dosage in their diet increases.
After the carnitine treatment begins, it is recommended that the dog have an EKG (echocardiogram) every three to six months to ensure the treatment has been effective.
There are no known methods of prevention, other than maintaining a healthy diet for your dog and monitoring for signs of deficiency, especially if your dog is a breed that is known to be affected by this condition.
