Did the vet do a lung x-ray? To rule out other reasons for the congestion? Most of my older dogs eventually have murmurs. But, your dog is young…. doesn’t mean that it might just be congenital and benign. Good luck, let us know what they find.

PS: For the age related murmurs, my dogs were never prescribed medication, as they were asymptomatic. No supplements were recommended either, just a healthy lifestyle and avoid high sodium foods.
