Mobility problems are among the most common conditions in the aging dog. There are several causes of this, one of which is called degenerative myelopathy (also referred to as DM). As the name suggests there is a deterioration of a crucial component of mobility. The word myelopathy refers to degeneration of the spinal cord, which is basically the highway allowing the brain to connect and communicate with the rest of the body.
In degenerative myelopathy, the spinal cord of the lower back (lumbar area) loses its signal conducting covering called myelin. When this happens, the brain cannot send messages along the spinal cord to the nerves, and the nerves cannot stimulate the muscles of the hind leg to move. As a result, the muscles of the hind legs weaken, lose the mass, and the dog loses control of its hind legs. Some breeds are more affected with this condition, particularly German Shepherds and Boxers, but it can occur in other breeds and in mixed breeds as well. The age of onset varies, but most dogs are in their senior years, but it can be found in middle aged dogs as well.
Signs of Degenerative Myelopathy
Many of the signs of DM are like arthritis and hip dysplasia
Changes in gait -swaying, wobbling, tripping, falling, dragging
Scuffing the top of the hind paws causing stubbed nails or bleeding nails
Crossing hindlegs
Atrophy of hind leg muscles
Inability to support weight in the hind legs
Fecal and urinary incontinence in the advanced stages
Diagnosis of Degenerative Myelopathy
Clinical symptoms and physical examination
Neurological examination
Radiographs and blood testing
DNA test to detect a gene mutation leading to this disease
Advanced diagnostics such as MRI and CT scan
Treatment of DM
Routine exercise to maintain muscle strength in the hind legs.
Physical therapy
Boot covers and paw grips to prevent injury and help with traction
Canine carts and support devices to help the pet to stand and move around
Maintaining proper hygiene
Several supplements have been used but their benefits have not proven consistent
Prognosis
DM is a progressive disease over months and many pet reach a disabled state within a year of diagnosis; at which time they are euthanized.
