Canine Multiple System Degeneration (CMSD) is a progressive neurological disorder involving degeneration across multiple regions of the central nervous system. Clinical signs usually appear between 10 and 14 weeks of age and include intention tremors, cerebellar ataxia, hypermetria, and impaired balance, often resulting in frequent falls. Due to the severity and progression of symptoms, most affected dogs are euthanized between 12 and 24 months to prevent further suffering.
Carrier status can be identified through DNA testing with our DNA test for CMSD in Chinese Crested Dogs (test code H165). This test is also part of the CombiBreed package for Chinese Crested Dogs with test code H514.
