Wobbler disease, or cervical vertebral instability, does rarely occur.

Wobbler disease is also known as cervical vertebral instability, cervical spondylomyelopathy (CSM), and cervical vertebral malformation (CVM).

Common serious health problems include dilated cardiomyopathy, cervical vertebral instability (CVI), von Willebrand's disease (a bleeding disorder for which genetic testing has been available since 2000; the test enables both parents of a prospective litter to be tested for the carrier gene, thus preventing inheritance of the disease ), and prostatic disease.
