What is degenerative myelopathy (DM)?
Degenerative myelopathy is a slowly progressive, non-painful disease of the spinal cord that causes gradual hind-limb weakness and loss of coordination. It most often affects older German shepherds, corgis, boxers and other predisposed breeds. There is no cure, but staying active can make a real difference.
Signs to watch for
- Scuffing or dragging back toenails
- Swaying or crossing back legs
- Trouble rising or slipping on smooth floors
- Slowly worsening weakness over months
How rehab helps
- Regular, structured exercise may help dogs stay mobile longer
- Maintains strength, balance and body awareness
- Adapts the home and fits harnesses, boots or carts as needs change
- Supports quality of life at every stage
What to expect in rehab for Degenerative myelopathy
Because DM is progressive, your dog's plan changes over time. Early on we focus on strength, balance and regular walking. Later we adjust exercises and help you choose harnesses, boots or a cart so your dog stays mobile and comfortable. Regular rechecks let us stay one step ahead of changes.
