What it is
The spine is a chain of small bones, the vertebrae, with cushioning discs between them and the spinal cord running through the middle. When a disc bulges or bursts, or a fall or knock damages the spine, the cord can be squeezed or bruised. The nerves then carry signals to the legs less well, which is why pain can come with wobbling, weakness or loss of movement.
Disc problems are linked to age and to build: dogs with a long back and short legs put more strain on the spine. Accidents, such as a jump from a height or a collision, can hurt any dog's back.
Stairs, jumping on and off furniture and rough play all load the spine. Ramps, rugs on slippery floors and lifting your dog with both the chest and the hindquarters supported make everyday life gentler on its back.
Signs you may notice
- Reluctant to jump or climb stairs
- Walks with a hunched back
- Yelps when picked up
- Trembles or pants while resting
- Wobbly or crossing hind legs
- Drags the legs or cannot stand
Be suspicious if the dog suddenly won't climb stairs or jump, walks hunched over, trembles, yelps when picked up, or starts to stumble on the hind legs. If the dog can't stand up or drags their legs, see a vet immediately.
When to see a vet
If your dog cannot stand, drags its legs or suddenly stops moving them, a vet is needed immediately. Back pain that makes your dog yelp, hunch or avoid moving is worth a vet visit as soon as possible.
