Spondylosis, arthritis of the vertebrae, on a Bulldog spinal radiograph showing bony bridging
Your vet X-rayed your bulldog for something else entirely and came back talking about his spine.
Spondylosis is arthritis of the vertebrae: chronic degeneration that throws up bone spurs along the edges and can eventually bridge one vertebra to the next. It sits mostly in the lower back, at the lumbar and lumbar sacral level.
Most bulldogs with it show nothing at all. That is why it is usually found by accident, and why finding it is not the same as needing to treat it.

Dr. K’s Quick Answer
Spondylosis is osteoarthritis of the spine. Repeated movement at the vertebrae that flex most causes bone on bone friction, the body throws up osteophytes along the vertebral edges, and adjacent vertebrae can fuse across the disc space in an attempt to stabilise the area. It is most common in the lumbar and lumbar sacral spine, and it turns up mostly in middle aged and senior bulldogs. The important thing to understand is that it is frequently subclinical: many bulldogs with clear spondylosis on film have no symptoms at all. So treat the dog, not the radiograph. When it does hurt, treatment is symptomatic, weight and pain control rather than surgery, which is rare here.

“Dr. Kraemer, my eight year old English Bulldog Sunny is showing signs of back pain. Could it be arthritis of the vertebrae, given his age and breed? And are there supplements or preventive measures that would help?”

Dr. Kraemer’s reply

At eight, spondylosis is a fair guess, and the lower back is exactly where it lives. But I would not let anyone settle on it without ruling out the others first, because several bulldog problems produce back pain and they are managed very differently. The diagnosis I care about is the one that explains the pain, not the one that shows up on the film. A physical exam should work through IVDD, vertebral malformation, hip dysplasia, an ACL injury, ordinary arthritis and a luxating patella before spondylosis gets the credit. That matters because spondylosis is frequently subclinical: plenty of bulldogs have obvious bony bridging on radiographs and no symptoms whatsoever, so finding it does not prove it is the source of Sunny’s discomfort. If it does turn out to be the cause, treatment is symptomatic rather than surgical. Get the weight off him, keep him moving for muscle support and blood flow, use an NSAID or an analgesic such as gabapentin when he needs it, and keep joint and comfort supplements going daily. Cold laser, PEMF and stem cell therapy all help with pain and inflammation without adding another drug.

Bulldog spondylosis is a form of vertebral arthritis characterized by chronic degeneration of the spinal column and tends to occur more frequently in the lower part of the spine.

Bulldog Spondylosis Vertebral Arthritis 5 X MUST KNOW

  1. Spondylosis in bulldogs is often subclinical and diagnosed during unrelated routine X-rays.
  2. Like common arthritis, it is often caused by degeneration due to chronic bone-on-bone injury
  3. Spondylosis is more common in the lower vertebra (lumbar-sacral)
  4. Treatment often requires pain and anti-inflammatory medication
  5. Prevention and care include weight management and Dr. Kraemer’s Bulldog Spondylosis and Back Care Bundles.

Spondylosis Vertebral Arthritis / CAUSE:

The exact cause of spondylosis in bulldogs is not well understood, but it is believed to be related to aging and the natural degeneration of the spinal discs. Factors that may contribute to the development of spondylosis include:

  1. CHRONIC INJURY: Similar to osteoarthritis in other joints, vertebral spondylosis is attributed to repeated injury, typically in areas of the vertebrae that undergo the most movement, leading to “bone on bone” friction.
  2. GENETIC: There might be a genetic underlining.
  3. CONFORMATION

Spondylosis Vertebral Arthritis AGE

Spondylosis vertebral arthritis in bulldogs is a chronic condition more common in middle-aged and older senior bulldogs. Younger bulldogs can also be affected, especially if they have a predisposition due to genetics or if they’ve experienced spinal trauma. bulldog spondylosis vertebral arthritis

Vertebral Arthritis in Bulldogs and French Bulldogs SYMPTOMS

Many bulldogs and Fr. bulldogs with spondylosis do not show any symptoms, especially in the early stages. When symptoms do occur, they can include:

  • Stiffness or reduced mobility
  • Pain in the back and hip area
  • Difficulty standing up, lying down, or climbing stairs
  • Limping or changes in gait
  • Visible discomfort when the spine is touched

Vertebral Arthritis in Bulldogs / DIAGNOSIS:

Vertebral arthritis in bulldogs is frequently subclinical, meaning it doesn’t always show obvious symptoms and is discovered incidentally during routine spinal radiographs intended for other purposes. Diagnostic tests are needed to recognize spondylosis deformans and to help exclude other diseases. Tests may include:

  1. EXAM: a physical exam should be conducted to help rule out other back and orthopedic problems, such as
    • IVDD
    • Vertebral Malformation
    • Hip Dysplasia
    • ACL Injuries
    • Arthritis
    • MPL: medial patella luxation
  2. IMAGING:  Radiographic 
  3. OTHER IMAGING:
    • myelogram
    • CT
  4. JOINT TAP: for analysis, cytology, and culture

BULLDOG AND FR. BULLDOG VERTEBRAL ARTHRITIS LOCATION

The arthritic fusion resulting from vertebral arthritis can occur in a single location, most frequently affecting the lower lumbar vertebrae or the lumbar-sacral region. However, it’s common for multiple vertebrae to be involved in the condition.

BULLDOG AND FR. BULLDOG VERTEBRAL ARTHRITIS BONE SPURS:

Vertebral arthritic changes often entail the development of bone spurs, medically referred to as “osteophytes.” These spurs can form along the edges of the vertebrae. Additionally, the condition can lead to the fusion of adjacent vertebrae across the intervertebral space, a process aimed at stabilizing the affected area but which can also contribute to pain and limited mobility.

Insider tip

Spondylosis is the most over blamed finding in bulldog medicine. It shows up on a film taken for a pre anesthetic check or an abdominal problem, it looks dramatic, and from that moment every stiff morning gets pinned on it. Meanwhile the actual source of the pain is very often somewhere else entirely, and usually somewhere treatable. In this breed that is most often the knee. So when a dog with radiographic spondylosis comes in sore, I still examine both knees, both hips and the neurological system before I accept the spine as the answer. The practical test is simple. If the pain is genuinely lumbosacral, it hurts on direct pressure over the lower spine and on extension of that region. If pressing the back does nothing and the dog is still limping, keep looking.
Bulldog spondylosis: quick answers
What is spondylosis, in plain terms?
Arthritis of the vertebrae. Chronic degeneration of the spinal column produces bone spurs, called osteophytes, along the edges of the vertebrae, and adjacent vertebrae can fuse across the disc space as the body tries to stabilise the area. That fusion can itself contribute to pain and reduced mobility.
The X-ray looks terrible. Is my bulldog in pain?
Not necessarily, and this is the single most useful thing to know about it. Many bulldogs with spondylosis show no symptoms at all, particularly early on, and the condition is usually discovered incidentally on radiographs taken for something else. The radiograph tells you it is present, not that it hurts.
What causes it?
The exact cause is not well understood, but it is tied to aging and natural degeneration of the spinal discs. Repeated injury at the vertebrae that move most leads to bone on bone friction, the same mechanism as osteoarthritis elsewhere. There is likely a genetic component, and conformation plays a part.
Where in the spine does it occur?
Most often the lower lumbar vertebrae or the lumbar sacral region. It can be a single site, but it is common for several vertebrae to be involved at once.
What signs would I actually see?
Stiffness or reduced mobility, pain in the back and hip area, difficulty standing up, lying down or climbing stairs, limping or a changed gait, and visible discomfort when the spine is touched.
How is it told apart from other back problems?
By examination first. A physical exam should rule out IVDD, vertebral malformation, hip dysplasia, ACL injury, general arthritis and MPL. Then radiographs, with myelogram or CT if needed, and a joint tap for analysis, cytology and culture where indicated.
How is it treated?
Symptomatically. Surgery is rare. Analgesics such as gabapentin or tramadol, NSAIDs for inflammation, plus stem cell therapy, cold laser and PEMF, and joint and comfort supplements daily. Prevention is the same short list that helps every joint in a bulldog: lean body weight, regular activity for muscle support and blood flow, and consistent supplementation.

Spondylosis on a radiograph is a finding, not a diagnosis. If your bulldog is genuinely sore, the examination matters more than the film, because IVDD, hip disease, a cruciate injury and a luxating patella all produce back and hind end pain and all need different handling. No supplement reverses bony bridging. What supplements do is manage the inflammation and pain, and support the muscle that takes the load off the spine.
