An enlarged heart could mean that your dog is developing heart disease but it could also just be normal for your dog. Your vet could submit a blood test called a proBNP which helps detect heart disease. You could also have a cardiologist perform an ultrasound of her heart to evaluate the function of her hear and measure the size.
