What it is
The cerebellum sits at the back of the brain and works like a quiet editor: it takes the rough instruction to move and adjusts its timing, force and direction, so that a paw lands exactly where it was meant to. When its cells are damaged or die off, the instruction still goes out, but nothing corrects it. Steps overshoot, the body sways, and the head may tremble as the dog homes in on a toy.
In the inherited forms the cells of the cerebellum gradually break down, so the clumsiness can slowly increase over months or years. In other cases inflammation, infection or a tumour is behind it.
Dogs can adapt surprisingly well to an unsteady gait and keep their zest for life. What helps is a home that forgives clumsiness: rugs on slippery floors, a gate at the top of the stairs, a steady, non-slip spot for the bowls, and walks on soft, even ground.
Signs you may notice
- Wobbly, swaying walk
- Legs lifted too high
- Wide-based stance
- Head tremor when reaching
- Misses the food bowl
- Trouble with stairs
You may notice a wobbly, clumsy gait, legs lifted too high, a wide-based stance or a head tremor when the dog tries to reach for something. Turning, climbing stairs or hitting the food bowl accurately can become difficult.
When to see a vet
Book a visit if your dog starts to move clumsily or the wobble gets worse. A dog that suddenly cannot stand or has a seizure needs a vet immediately.
