Paralysis - sudden onset

Paralysis is the inability to move one or more limbs. There are many different disease processes that can cause a slowly progressive weakness or paralysis in dogs and cats.

This section deals with an acute (or sudden) onset of paralysis.

Acute paralysis (developing suddenly or over minutes to hours) is always an immediate emergency.

There are numerous causes of sudden paralysis. The most common causes are:

  • Spinal injury/trauma from falls, fights, and hit-by-car
  • Intervertebral disc disease/bulging disc (common in small dogs especially dachshunds)
  • Blood vessel clot (cats) - commonly referred to as "saddle thrombus"
