Acute Spinal Cord Injury
A Pet Parent's Guide to Sudden Back Pain and Paralysis
There are few things more terrifying for a pet parent than watching their previously healthy dog suddenly cry out in pain and lose the ability to use their legs. Acute spinal cord injuries happen fast, often without any major trauma like a fall or a car accident. Sometimes, it happens just from jumping off the couch.
The spinal cord is like a thick fiber-optic cable that carries messages between your dog's brain and the rest of their body. When that cable is bruised, pinched, or crushed, the signals get blocked. The severity of the injury dictates whether your dog just has a wobbly walk, or if they are completely paralyzed.
How Bad Is It? (The Stages of Injury)
Veterinarians grade spinal cord injuries from mild to severe to determine the best treatment and the likelihood of recovery:
- Stage 1 (Pain only): Your dog can walk normally, but they are in severe pain. They may tremble, pant, or refuse to lower their head to eat.
- Stage 2 (Wobbly): The signals are getting scrambled. Your dog can walk, but their legs cross over each other, or they occasionally knuckle their paws over.
- Stage 3 (Weakness): Your dog can still move their legs voluntarily, but they are not strong enough to stand up or support their own weight.
- Stage 4 (Paralysis with feeling): Your dog cannot move their legs at all. However, if we firmly pinch their toes, they cry out or look at us, proving the brain is still receiving "pain" signals from the foot.
- Stage 5 (Paralysis without feeling): The most severe stage. The spinal cord is so damaged that the signal is completely cut off. The dog cannot move their legs, and they do not feel a firm pinch to the bone of their toe.
Why We Need Advanced Imaging
Standard X-rays are great for looking at bones, but the spinal cord and the intervertebral discs are made of soft tissue, which makes them invisible on an X-ray. An MRI is the only way to image the spinal cord and discs directly, however a CT-myelogram and an Xray-myelogram may also allow a surgeon to see where the spinal cord is pinched, and determine if surgery will help.
Treatment Options: Rest vs. Surgery
Medical Management (Strict Rest): If your dog has a very mild injury (Stages 1 or 2), or if the MRI shows the cord is only bruised but not compressed, we will likely recommend medical management. This involves powerful pain medications and absolute, strict crate rest for 4 to 6 weeks to allow the body to heal. No running, jumping, or playing is allowed.
Spinal Surgery: If your dog has a severe injury (Stages 3, 4, or 5) caused by a slipped disc pressing against the spinal cord, surgery is usually required. Our surgical team will carefully remove the bone over the spinal canal and extract the disc material to relieve the pressure on the cord. For dogs in Stages 1 through 4, the success rate of surgery is typically excellent (85-90%). For dogs in Stage 5, emergency surgery is required immediately to give them a 50/50 chance of walking again.
The Road to Recovery
Recovery from a spinal injury is a marathon, not a sprint. Even after successful surgery, your dog may need help using the bathroom for a few weeks, and they will require intensive physical rehabilitation (like underwater treadmills and targeted exercises) to retrain their muscles and nerves how to work together again. Our team will be with you every step of the way to guide your dog's rehabilitation journey.
