What it is
Neurons are the cells that carry messages through the brain and spinal cord, and unlike skin or bone cells, they are not replaced once lost. In neuronal degeneration they fail one by one, and the parts of the nervous system they belong to slowly lose their grip on the jobs they do. Which signs appear depends on where the loss happens: the areas that coordinate movement, keep balance or shape behaviour.
The name covers a group of conditions rather than a single disease. Some are inherited and can show up in a young dog; others develop later in life.
Living with a dog whose coordination is changing means making the world a little safer: rugs on slick floors, a gate at the top of the stairs, a harness rather than a collar on walks, and a steady routine the dog can follow even as its body becomes less reliable. Its interest in smells, food and people can stay bright while its movements change.
Signs you may notice
- Wobbly, unsteady gait
- Uneven or high steps
- Loses balance easily
- Trembling of head or body
- Changes in behaviour
You may notice a dog that starts to wobble, places its feet unevenly, has more trouble keeping its balance, trembles, or whose behaviour changes. If movement or behaviour changes for no clear reason, it is worth having the dog seen by a vet.
When to see a vet
Book a visit if your dog starts to wobble, stumble or behave differently for no clear reason; a short video of it helps. If it has a seizure or suddenly cannot stand, a vet is needed immediately.
