Dilated Cardiomyopathy
What is it?
Dilated cardiomyopathy (DCM) is a heart disease in which the heart muscle weakens and the heart enlarges. It is seen mainly in middle-aged and older ferrets.
What signs should I watch for?
Signs to watch for include tiring easily, weakness; rapid or labored breathing, coughing; swollen belly from fluid; weight loss; and pale or bluish gums.
How is it diagnosed and treated?
Chest X-rays, an ECG, and an echocardiogram confirm the diagnosis. Treatment uses heart medications and fluid-control medicines, sometimes with fluid removal.
Can it be prevented, and what's the outlook?
- DCM is managed rather than cured; many ferrets improve on medication.
- Ferrets should not have heartworm ignored either; ask about prevention.
