Spondylosis in dogs is a common condition that may or may not be an “expected” byproduct of aging. On the blog this week, Dr. Julie Buzby, integrative veterinarian and founder ofDr. Buzby’s ToeGrips®,shares the nitty-gritty on spondylosis in dogs. By the end of this article, you’ll have the answers your senior dog wants you to know.
As a veterinarian with more than 20 years of experience caring for senior dogs, I’ve seen a lot of dog spines with spondylosis. The X-rays can be dramatic and scary, but the story is often rather mundane. In this article, we’ll explore what spondylosis is, its causes, symptoms, and risk factors, plus take a look at how vets diagnose this condition. Lastly, I’ll share treatment options that have the potential to make a big difference in your dog’s quality of life.
What is spondylosis in dogs?
First, let’s answer the question, “What is spondylosis in dogs?” Spondylosis deformans, as it is formally called, is a degenerative condition that affects a dog’s vertebrae—the bones that make up the spinal column and protect the spinal cord. In many cases, spondylosis is considered a normal part of aging for older dogs.
Dogs with spondylosis deformans often do not show any outward symptoms at all. Perhaps it’s because of my training and certification through the American Veterinary Chiropractic Association, but I also believe that dogs can display signs of pain and “restriction” of movement related to spondylosis.
What causes spondylosis?
In order to better understand spondylosis in dogs, it helps to know a little bit about the anatomy of a dog’s spine.

Similar to humans, your dog’s spinal cord is a large bundle of nerves that connects to the base of the brain and runs down the neck and back. Nerve roots from different parts of the spinal cord send signals from the brain to the rest of the body. Without this part of the nervous system, dogs can’t walk or perform their everyday tasks.
To protect this nerve highway, individual bones (vertebrae) encase the spinal cord. Spaces between the vertebrae are the joints that help maintain the back’s flexibility. The spinal cord is further protected by intervertebral discs—small, soft pads that act as cushions or shock-absorbers.

For the most part, the cause of spondylosis in dogs is simply the normal wear and tear on the fibers of the ligaments that connect the intervertebral discs to the ends of the vertebral bodies. As stress and strain cause microtears in these fibers, and subsequently instability, the body tries to compensate by laying down new bone (bone spurs) on the ends of the vertebrae and eventually “bridge the gap.”
What do I mean by this? Bone spurs can grow large enough that they touch neighboring spurs and form a bridge. This is known as “bridging spondylosis.” These bridges typically form along the vertebrae in the middle of the back – the thoracolumbar spine – and most commonly form along the lumbar spine in the lower back.

What are the risk factors for spondylosis?
Spondylosis affects large breed senior dogs and some middle-aged smaller breed dogs. As explained in an abstract from the National Library of Medicine (NIH), it is commonly seen in Boxers, which suggests there may be a genetic predisposition.
Conditions that cause disruption to the joints of the spine increase the risk of developing spondylosis. For example, if a dog suffers a traumatic injury that causes compression of the intervertebral disc spaces, the resulting joint instability increases the risk of bone spurs developing in this area.
Similarly, a dog with intervertebral disc disease may go on to develop spondylosis in the affected area since the diseased discs have resulted in instability for those joints.
Essentially, spondylosis is the body’s attempt to stabilize instability in the joints of the spine by laying down extra bone to guard them.
What are the symptoms of spondylosis in senior dogs?
As I said above, in most cases, dogs with spondylosis don’t show any outward symptoms. The classic changes in the backbone that we see with spondylosis are not usually responsible for pain and lameness. Rather, the condition is most often found incidentally while diagnosing another health condition.
The unique X-ray (radiograph) below perfectly illustrates how spondylosis in dogs is often diagnosed. My colleague, Dr. Jaime Wright Carroll, saw this patient not for back problems, but for gastrointestinal distress. After a physical exam and X-rays, Dr. Carroll diagnosed the 13-year-old hound dog with gastric dilatation and volvulus—commonly known as bloat in dogs. Take a look at this X-ray. Do you see anything odd?

Yep! You guessed it. There is a “foreign body” in that huge stomach. At some point prior, this poor dog had swallowed a yellow rubber ducky! The X-rays show a large, twisted, gas-filled stomach—a serious veterinary emergency.

Dr. Carroll was unsure if the rubber toy was a red herring unrelated to the bloat or if it had acted like a roadblock to the normal flow of digestion, leading to bloat. But along with bloat, Dr. Carroll found spondylosis in the dog’s spine. If you look close on the X-ray, you’ll see the telltale bone spur “bridges.”
3 signs of spondylosis
Your dog may or may not display symptoms from this “reshaping” of the vertebrae. Here are a few things to watch for on behalf of your senior dog:
- Changes in walk: Instead of smoothly swaying from side to side, you may see your dog’s back stiffen and fail to move freely.
- Change in movement: Your dog’s back may seem rigid, and he may avoid ambitious movements like jumping up or rolling over.
- Change in comfort level: If your dog’s bone spurs begin to pinch the delicate nerve roots along the spinal cord, he may show signs he is in pain and be very sensitive to touch along his back.
How does a vet diagnose spondylosis in senior dogs?
Your vet will use X-rays to diagnose spondylosis since the distinctive bone spurs show up easily on X-rays. If your vet suspects damage to the spinal cord or inflammation of the nerves, he or she may also recommend advanced imaging. An MRI or CT scan can rule out other issues and ensure appropriate treatment.

How do you treat spondylosis in dogs?
If your dog has spondylosis but isn’t experiencing pain or discomfort, he may not need treatment right away…or ever. But if your veterinarian shares my thinking, he or she may recommend joint supplements because they have a protective effect on joints.
Ingredients like glucosamine and chondroitin help keep joints flexible and healthy. Therefore, supplements may be helpful in slowing the development of spondylosis.And although I believe that the best supplement for joint pain in dogs is not just about joints, my go-to product recommendation for protecting the health of the joints between the vertebrae is Encore Mobility™ with Green Lipped Mussel and New Zealand Deer Velvet.
In very rare cases, surgery may be necessary to remove spurs that are pressing upon the spinal cord, but I’ve never seen this scenario in my entire career.

If your senior dog is experiencing back pain, it’s most likely not coming from spondylosis. Anything’s possible, but there’s a laundry list of conditions that I’d be concerned about before pinning the pain on spondylosis.
But whatever the root cause, your dog may benefit from anti-inflammatory medications and/or medications for nerve pain. These are often able to provide relief for back pain. Also, veterinary acupuncture, animal chiropractic, and physical therapy are highly effective methods for mitigating pain and improving mobility for these dogs.

If your dog is overweight, this is the #1 thing you must address to protect your dog’s spine. Your veterinarian can help you formulate a personalized diet plan. Lower calorie foods and controlled exercise can facilitate weight loss. If you’re unsure whether your dog is overweight, you’ll want to “find your dog’s number” on our canine body condition score chart.
Since present-day pups live longer than their predecessors, they’re more susceptible to joint damage and inflammation over time. Joint inflammation is commonly known as canine arthritis. Spondylosis has been likened to arthritis in the spine. However, unlike arthritis, there is not an inflammatory component with the bony changes. This is a blessing because inflammation means hurting.
A common disease in senior dogs
Often diagnosed as an incidental finding, spondylosis deformans is a common disease in senior dogs. Though veterinarians debate this, I believe spondylosis can be painful. We know spondylosis in humans can be painful. Knowing what to watch for can help prevent your dog from experiencing unchecked discomfort. Your veterinarian will have your dog’s back on this one (pun fully intended!) But as veterinarians, we’re trained to treat the dog, not the X-rays. Sometimes a dog can have horrific radiographs and no apparent pain…or have very mild changes on radiographs and tremendous stiffness and soreness.
Even if your dog’s spondylosis diagnosis is believed to be an incidental finding not associated with problems, ask your vet how you can be more intentional and proactive in maintaining mobility. Your dog (and his spine) will thank you for it!

FAQs
Spondylosis in Dogs: What Your Senior Dog Wants You to Know? ›
The disease is caused by the abnormal growth of bone in the spine and leads to progressive weakness and pain. Dogs that are affected by spondylosis often show signs of pain, reluctance to move, and difficulty standing or walking. The condition is diagnosed based on physical examination and spinal radiographs (x-rays).
How can I help my dog with spondylosis? ›If the pet appears to be painful, non-steroidal anti-inflammatory drugs (NSAIDs) or other analgesics may provide relief. Physical therapy, weight loss, and controlled exercise programs may be helpful in some cases.
Should I walk a dog with spondylosis? ›If your dog has spondylosis, you may want to choose lower impact choices, like swimming and walking over running and retrieval games. Any dog exhibiting signs of pain would probably benefit from a nonsteroidal anti-inflammatory prescribed by your veterinarian.
What supplements are good for dogs with spondylosis? ›Ingredients like glucosamine and chondroitin help keep joints flexible and healthy. Therefore, supplements may be helpful in slowing the development of spondylosis.
Can spondylosis in dogs cause incontinence? ›Incontinence. Occasionally with spondylosis, there can be neurologic impairment if a nerve is involved. For instance, some pets with spinal trauma may have issues with incontinence. This can be a result of interrupted communication on the spinal cord due to the impingement of bone spurs.
What aggravates spondylosis? ›Lumbar Spondylosis Degeneration in the lumbar spine may cause pain in the back, buttocks, or legs, with possible numbness, and muscle weakness that may be worsened by activities such as lifting, bending, twisting, or sitting.
What should you not do with spondylosis? ›There should be restriction of heavy lifting; excessive bending, twisting, or stooping; and avoidance of any work or recreational activities that cause stress to the lumbar spine. Your physician will outline a rehabilitation program to return you to your activities as soon as possible.
How do you prevent spondylosis from getting worse? ›There is no way to prevent cervical spondylosis as this condition is a normal, age-related deterioration (“wear and tear”) of the joint space and disks in your neck.
Does drinking water help with spondylosis? ›If you have ankylosing spondylitis (AS), you're probably familiar with the daily burden of managing pain and fatigue. But good habits can help reduce your most bothersome symptoms. That's why it's important to follow a healthy lifestyle, which includes drinking enough water.
Does spondylosis get worse in dogs? ›The body weight of a dog may influence the emergence and progression of most degenerative joint diseases including Spondylosis. This is simply because a bigger body will have more pressure being applied to the affected area, which worsens it.
How do you stop the progression of spondylosis? ›
A combination of aerobic, strength-building, stretching, and balancing exercises is best. Work with a physical therapist (PT) on a safe and effective exercise plan. An anti-inflammatory diet may also help keep AS from getting worse.
What food is good for spondylosis? ›Eat a variety of healthy foods rich in antioxidants, such as colorful vegetables and fruits. Eat foods rich in omega 3 fatty acids, such as salmon, flax seeds, and certain nuts. Use fat (especially saturated fat found in animal products), cholesterol, sugar, and salt in moderation.
What is the difference between spondylitis and spondylosis in dogs? ›Learn the difference between the two, what causes them, and how they are treated. Spondylitis occurs due to inflammation that causes arthritis while spondylosis is the wear and tear of the vertebrae, resulting in the disk and joint degeneration.
Can spondylosis cause bowel problems? ›Between 5 and 10% of cases of ankylosing spondylitis (AS) are associated with inflammatory bowel disease (IBD), either Crohn's disease or ulcerative colitis. A much larger percentage of AS patients have subclinical gut inflammation manifested either by endoscopic findings or by histology.
What does gabapentin do to dogs? ›While for humans gabapentin is used to treat partial seizures, nerve pain, and restless leg syndrome, for dogs it is used to treat seizures, anxiety, and nerve pain. It works by blocking calcium channels in the brain to suppress overly stimulated neurons that cause anxiety, nerve pain, and seizures.
What is the most serious complication of spondylosis? ›Spondylosis can lead to spinal stenosis, which is a narrowing of the spinal canal. As a result, the spinal cord and/or spinal nerve roots can become compressed (pinched). For example, the cervical spinal cord can be affected by compression from spondylosis. This is called cervical spondylotic myelopathy.
What is the prognosis for spondylosis in dogs? ›The prognosis for dogs with spondylosis is generally good. Dogs only require therapy if they are showing clinical signs and if they are, they typically respond well to treatment. Treatment may be required lifelong as symptomatic spondylosis in dogs is a progressive condition.

- Weakness in your arms and legs.
- Numbness in your shoulders, arms, or hands.
- Stiffness in the neck.
- Trouble keeping your balance.
- Trouble controlling your bladder or bowels.
Spondylosis is caused by chronic wear on the spine. This includes the disks or cushions between the neck vertebrae and the joints between the bones of the cervical spine. Over time these changes can press down on (compress) one or more of the nerve roots. In advanced cases, the spinal cord becomes involved.
What is the best vitamin for spondylosis? ›Calcium is essential for healthy bones, and vitamin D is essential for your body to absorb calcium, making these two nutrients important for people with ankylosing spondylitis.
