Treatment for heart disease in dogs depends on what type of heart problem they have, what has caused it, and what stage of heart disease your dog is in. If your dog is in the early stages, your veterinarian will most likely want to monitor the condition and ask you to return for regular check-ups.
Common treatments for heart disease in dogs include medication, lifestyle changes, and surgery.
