Getting him to the vet soon is good. First you need to find out what is truly wrong. Cardiomyopathy is usually seen with a chest x-ray. It can be treated with some inexpensive medicines, some cost more than others, however. If you are recommended one that is costly it would be good to shop around for a discount place. The one dog I had was on a very expensive medicine if I bought it at the pharmacy but when I bought it from the veterinary teaching college it was 1/4 the price! I would ask your vet for help on discount or a prescription so you can shop around with the internet or elsewhere.
