Recent studies have shown that many golden retrievers are being diagnosed with taurine deficiency and dilated cardiomyopathy (DCM). If left untreated congestive heart failure and possibly death can occur. In the past this wasn’t a problem for goldens. It occurred in larger dogs.
We have compiled information from several sources for your education and awareness and for your discussion with your veterinarian.
It is felt that the grain free foods may play a major part in taurine deficiency. 
Peas, beans, pea starch, legumes, potatoes and sweet potatoes have replaced the grains as the carbohydrate in most dog foods. These block the function of taurine.

The veterinary cardiologists and nutritionists are unanimous in their assessment that the best way to get your dog out of danger in this situation and to protect your dog from future problems is to buy your dog food from a “company this is committed to resolving this problem” and is involved in the scientific research.

You can have your own Golden Retriever tested by your vet. A whole blood sample is taken and sent to UC Davis. 250 nmol/L is a minimum normal Taurine level for a Golden Retriever.
Information on sending sample to UC Davis
If the taurine level is below normal, an echocardiogram is recommended. Low taurine levels and DCM can be reversed if caught early enough.
Signs and symptoms of DCM are: pale gums, lethargy, cough, weakness, rapid heart rate, rapid breathing or exercise intolerance.
Always consult with your vet to discuss the right solutions for your dog.
