Canine Distemper
What is it?
Canine distemper is a virus that is almost always fatal in ferrets. It spreads through the air and contact with infected animals, including dogs and wildlife.
What signs should I watch for?
Signs to watch for include eye and nose discharge; fever, loss of appetite; rash on the chin and groin; thickened, crusty footpads; and neurologic signs such as tremors or seizures.
How is it diagnosed and treated?
Diagnosis is based on signs and lab testing. There is no effective treatment, and humane euthanasia is often recommended to prevent suffering.
Can it be prevented, and what's the outlook?
Vaccination with a distemper vaccine approved for ferrets is essential, even for indoor ferrets.
