Dogs have seven lumbar vertebrae, which are located in the lower back, connecting the spine and the pelvis. The lumbar region of a dog's spine is susceptible to several conditions, including lumbosacral disease, intervertebral disc disease (IVDD), and degenerative myelopathy (DM). These conditions can cause back pain, incontinence, loss of coordination, and weakness in the hind legs. Treatment options range from conservative medical treatment to surgical intervention, depending on the severity and duration of symptoms.

The backstrap, or the dog's lumbar muscles, are thick, smooth, and solid to touch
The backstrap is an important muscle group for dogs, and any restriction or weakness along the muscle sides of the spine can affect all body functions. For example, lateral and forward movement may be impaired, and inhalation and exhalation may be reduced. Problems in the back muscles may be indicated by twitching and tenderness along the back and rib cage muscles. Massage can be used to manipulate the fascia of the backstrap, with light to light-medium pressure to avoid increasing discomfort.
The lumbar spine, or lower back, is a common site of spinal issues in dogs. Intervertebral disc disease (IVDD) is the most common cause of back pain in dogs, and can lead to herniated or "slipped" discs, causing severe signs such as paralysis. Large breeds of dogs, especially German Shepherds, are prone to degenerative lumbosacral stenosis, a disorder causing compression of the nerve roots. This condition typically presents with signs such as difficulty using the hind legs, tail weakness, and incontinence.
Diagnosis of lumbosacral issues may involve advanced imaging such as magnetic resonance imaging (MRI) or computed tomography (CT), as well as a thorough clinical history and physical examination. Treatment options depend on the specific condition and can range from conservative medical treatment to surgical intervention.

Lumbosacral disease is caused by a narrowing of the spinal canal, compressing nerves
The lumbar region of a dog's spine consists of seven lumbar vertebrae, which are held together by thick supraspinous ligaments. The backstrap, a muscle group that encompasses these vertebrae, is thick, smooth, and solid to the touch. It supports virtually every muscle in the dog's body, including the sublumbar muscles, which allow the trunk to be flexed or pulled tightly to the caudal.
Lumbosacral disease is a condition caused by a narrowing of the spinal canal, which results in the compression of the spinal nerve roots. This compression can be caused by arthritis, intervertebral disc herniation, infection in the disc, trauma, congenital malformation, or a spinal tumour. The most common causes are arthritic degeneration and intervertebral disc herniation. Lumbosacral disease occurs most often in middle-aged to older large-breed dogs, such as German Shepherds.
The clinical signs of lumbosacral disease are caused by the narrowing of the spinal canal and the pressure exerted on the nerves that exit the spine. This can lead to neurological issues such as weakness or paralysis in the rear legs, and incontinence. If there is discospondylitis, antibiotics are required, although infection is not a common cause of lumbosacral disease.
Treatment for lumbosacral disease can be either conservative medical treatment or surgical intervention. Conservative treatment includes weight reduction for overweight dogs, as excessive body weight aggravates any disorder of the back. Strict rest is also essential to the success of medical treatment. Anti-inflammatory drugs and pain relievers often provide temporary pain relief and may improve clinical signs. If conservative management is unsuccessful, surgery may be necessary to relieve pressure on the spinal cord.

Conservative treatment for lumbosacral issues includes weight reduction, rest, and medication
The lumbar vertebrae in dogs are part of the spine, connecting the pelvis and the lumbar spine. The backstrap, or the intervertebral muscles, are the muscles that run from one vertebra to the next along each side of the spinal column. These muscles support the dog's movement and protect the spine.
Lumbosacral disease, a condition caused by the narrowing of the spinal canal, often affects middle-aged to older large-breed dogs. It results in the compression of the spinal nerve roots. Treatment for lumbosacral disease depends on the severity and duration of the condition, as well as owner preferences. Conservative treatment methods are often the first line of defence and include:
- Weight reduction: Excessive body weight can aggravate any disorder of the back. Weight reduction is an important part of conservative treatment, especially if the dog is overweight.
- Rest: Strict rest is crucial for the success of any acute back problem treatment. Cage rest is preferable, but confinement to a small, fenced area or room may also be acceptable.
- Medication: Anti-inflammatory drugs (e.g., meloxicam) and pain relievers (e.g., gabapentin) can provide temporary pain relief and improve clinical signs. Antibiotics may be required if there is an infection in the disc, although this is uncommon. Other medications used in conservative treatment for similar conditions in humans include acetaminophen, NSAIDs, opioids, and calcitonin.
If conservative management is unsuccessful, or if there are recurrent pain and neurological signs, surgical treatment may be necessary.

Surgery may be required for recurrent pain, neurological signs, or paralysis
Recurrent pain, neurological signs, or paralysis in dogs can be caused by lumbosacral disease, also known as cauda equina syndrome. This condition affects the lumbosacral junction in the lower back, where the lumbar vertebrae meet the sacrum. The most common causes of lumbosacral disease are arthritic degeneration and intervertebral disc herniation, which result in the narrowing of the spinal canal and compression of the spinal nerve roots. Other causes include infection, trauma, congenital malformation, or a spinal tumour. The disease occurs most frequently in middle-aged to older large-breed dogs, such as German Shepherds.
Treatment options for lumbosacral disease include conservative medical treatment or surgical intervention. Conservative treatment involves weight reduction for overweight dogs, strict rest, and the use of anti-inflammatory drugs and pain relievers such as meloxicam (Metacam®) and gabapentin. Antibiotics are required in the case of disc infection (discospondylitis), although this is uncommon.
However, if conservative management fails to provide relief, or if the dog exhibits recurrent pain, weakness, or paralysis, surgical treatment becomes necessary. The recommended surgical procedure is called a dorsal laminectomy, which relieves the pressure on the spinal cord caused by a bulging or ruptured disc. This surgery is expected to provide pain relief and improved rear leg function. The prognosis depends on the severity and duration of the condition, and any permanent nerve damage will not be reversed.
Spinal surgery in dogs is a major procedure and carries risks such as bleeding, infection, and nerve trauma. It is typically performed under general anaesthesia by a neurosurgery specialist. During the surgery, cuts are made in the vertebral column to relieve pressure on the spinal cord. Post-operative recovery can be challenging, and significant pain management may be required.
In summary, surgery is considered for dogs with recurrent pain, neurological deficits, or paralysis resulting from lumbosacral disease or other spinal conditions. The decision to proceed with surgery depends on the severity of the condition, the owner's preferences, and the response to conservative management. While surgery can provide relief and improve function, it also carries risks that owners should carefully consider in consultation with a veterinary specialist.

Degenerative lumbosacral stenosis is a disorder of the vertebrae causing nerve compression
The lumbar area of the spine is located in the lower back and consists of five vertebrae that connect the upper spine to the pelvis. Degenerative lumbosacral stenosis is a disorder of the vertebrae causing nerve compression. It is a condition caused by the narrowing of the spinal canal, resulting in compression of the spinal nerve roots. This compression can lead to pain, numbness, and weakness in the legs, making it difficult to walk or get out of a chair. In more severe cases, it may cause issues with bowel and bladder control.
Lumbosacral disease occurs most frequently in middle-aged to older large-breed dogs, such as German Shepherds. The condition is caused by a narrowing of the spinal canal, which can be due to various factors such as arthritis, intervertebral disc herniation, infection, trauma, congenital malformation, or a spinal tumour. The most common causes are arthritic degeneration and intervertebral disc herniation.
The treatment for lumbosacral disease in dogs depends on the duration and severity of the symptoms, as well as owner preferences. Conservative medical treatment includes weight reduction, strict rest, anti-inflammatory drugs, pain relievers, and antibiotics in the case of an infection. If conservative management is unsuccessful or if neurological signs are present, surgical intervention may be necessary to relieve pressure on the spinal cord. This may include a procedure called a dorsal laminectomy.
In humans, lumbar spinal stenosis is typically diagnosed through a physical exam and imaging techniques such as X-rays, CT scans, or MRI scans. Treatment options include physical therapy, medication, and, in some cases, surgery. Physical therapy focuses on strengthening the back, stomach, and leg muscles, learning safe activities, using braces, stretching, and massage. Medications can include non-steroidal anti-inflammatory drugs, steroid injections, and muscle relaxants. Surgery may be considered as a last resort and involves procedures such as removing bone spurs, widening the space between vertebrae, or fusing vertebrae to stabilise the spine.
