Spondylosis in Dogs: Stiff Spines in Older Dogs

6 min read Vet-informed guidance

Spondylosis deformans is a degenerative change where bony spurs form along the spine. It’s very common in older dogs and often causes no symptoms at all — but in some dogs it leads to stiffness and reduced flexibility. Here’s how to recognise it and help.

What is spondylosis?

Over time, bony bridges (osteophytes) can form between the vertebrae of the spine, usually as a response to ageing and wear. In many dogs they’re an incidental finding on an x-ray. In others, they reduce the spine’s flexibility and cause stiffness or discomfort.

Signs it might be bothering your dog

Because it develops slowly, signs are easy to put down to ageing.

  • Stiffness, especially after rest or in cold weather
  • Reduced flexibility — turning or twisting less easily
  • Reluctance to jump or climb
  • A slightly stiff or 'roached' posture

Keeping the spine supple

Gentle, regular movement and good support are the cornerstones of management.

  • Little-and-often exercise to keep the back mobile
  • A supportive orthopaedic bed and warm rest areas
  • Ramps to avoid jarring the spine jumping on and off furniture
  • Keep your dog lean to reduce strain
  • Joint and mobility support as part of a routine

When to see your vet. See your vet if your dog seems painful, suddenly stiffer, or develops any weakness or wobbliness in the back legs, as this needs investigating to rule out other spinal conditions.
