Do all dogs get degenerative myelopathy?

Degenerative myelopathy is an autosomal recessive genetic disease, meaning inheriting one or two copies of the gene (SOD1), increases the risk of developing the disease; however, not all dogs who carry even both genes will develop DM.

Can a dog have degenerative myelopathy without the gene?

The disease is inherited in an autosomal recessive fashion with incomplete penetrance, and is caused by a mutation (c. 118G>A) in the gene SOD1. Thus, two copies of the SOD1 mutation (DM/DM) confer increased risk for DM but not all DM/DM dogs across breeds will develop the disease.
