What is spondylosis?

Vet at FirstVet answers:

Spondylosis is a term used to describe bony changes between the vertebra in the back. It develops over time and is therefore usually seen in older dogs (unless in boxers when it can be a hereditary condition). If found in the lower back it is usually a sign that the dog has a problem with vertebral instability (usually between L7-S1). This instability is painful and is suspected if the dog does not want to jump up onto things or move around as much as it usually does. With time, changes in the vertebra causes them to conjoin, resulting in a stiff back.
