Was ist Spondylose beim Hund?

Spondylosis deformans ist die Bildung von Knochenspornen an den Wirbelkörperrändern — ein degenerativer Alterungsprozess. Oft asymptomatischer Zufallsbefund im Röntgen. Bei Symptomen: Rückensteifheit und chronischer Schmerz, besonders nach Ruhephasen.

Wie unterscheidet sich Spondylose von einem Bandscheibenvorfall?

Spondylose ist chronisch-degenerativ mit Knochenspornen und verursacht Steifheit und chronischen Schmerz. IVDD entsteht durch Bandscheibengewebe im Rückenmarkskanal und verursacht akute Lähmungszeichen. MRT für IVDD, Röntgen für Spondylose.

Wie wird Spondylose beim Hund behandelt?

Asymptomatische Spondylose benötigt keine Behandlung. Symptomatisch: NSAIDs, Gewichtskontrolle, Physiotherapie und Hydrotherapie als Erstlinientherapie. Chirurgie nur bei schwerer neurologischer Beeinträchtigung durch dorsale Kompression.

Spondylosis in Dogs: Causes, Symptoms, and Treatment

Spondylosis deformans is a degenerative spinal condition in which bony growths (osteophytes) form on the edges of the vertebral bodies and intervertebral discs. These bone spurs grow beyond the edges of the vertebral bodies and can connect adjacent vertebral bodies (bone bridges). Spondylosis is a degenerative, age-related process – it is often an incidental finding on X-rays and does not necessarily cause symptoms.

Spondylosis in Dogs: Causes, Symptoms, and Treatment

What is spondylosis in dogs?

Spondylosis deformans is a degenerative disease of the spine in which bony growths (osteophytes) form along the edges of the vertebral bodies and intervertebral discs. These bone spurs extend beyond the edges of the vertebral bodies and can bridge adjacent vertebral bodies (bone bridges). Spondylosis is a degenerative, age-related process—it is often an incidental finding on X-rays and does not necessarily cause symptoms.

Spondylosis is not the same as intervertebral disc disease (IVDD)—it primarily affects the outer parts of the disc-vertebra junction, not the disc nucleus.

Background + Scientific Context

In his seminal study, Morgan (1999, *Acta Orthopaedica Scandinavica Supplement, https://pubmed.ncbi.nlm.nih.gov/10472665/) describes the morphology and clinical observations of canine spondylosis deformans: Spondylosis results from mechanical stress and degenerative changes at the disc-vertebral body junctions (disc-endplate interface). Osteophytes form primarily ventrally and laterally to the vertebral bodies—they grow toward the adjacent vertebra and, in severe cases, can form bony bridges. Particularly frequently affected: the thoracolumbar transition region (T11–L3) and the lumbosacral segments. Breeds with increased incidence: Boxer, German Shepherd, Airedale Terrier. In many dogs, spondylosis is asymptomatic—paradoxically, the bony bridges stabilize the degenerated segment.

Brisson (2010, *Veterinary Clinics of North America*, https://pubmed.ncbi.nlm.nih.gov/20732592/) describes the differentiation from spondylosis in the context of intervertebral disc diseases: While IVDD causes spinal cord compression through prolapse or protrusion of the disc nucleus, spondylosis primarily compresses nerves through osteophytes that grow laterally or dorsally and impinge on nerve roots. Clinical differences: IVDD typically causes acute to subacute signs of paralysis; spondylosis causes chronic stiffness, pain on movement, and gait abnormalities without complete paralysis. Imaging differentiation: on conventional X-rays, spondylosis appears as bone spurs; IVDD often requires MRI for localization of the prolapse.

Ettinger et al. (2017, *Textbook of Veterinary Internal Medicine*) describe management and prognosis: Treatment is not necessary for asymptomatic spondylosis—monitoring and weight control are sufficient. For symptomatic spondylosis (pain, stiffness, gait abnormalities): NSAIDs (carprofen, meloxicam) are the first-line therapy; physical therapy and hydrotherapy improve mobility and muscle condition; acupuncture has been shown in clinical studies to have an analgesic effect on spinal pain. Surgery is rarely indicated—only in cases of severe neurological impairment caused by dorsal osteophytes.

Vitomalia-Position

Spondylosis sounds serious—but it is usually an X-ray finding with no clinical significance. Many older dogs with radiographic spondylosis are asymptomatic. If pain or limited mobility is present, conservative management is highly effective. Overdiagnosis and overtreatment are more common than underdiagnosis.

When does spondylosis become a concern?

Older dog with progressive stiffness in the back when standing up
Stiffness after rest, improvement after brief activity
Reluctance to climb stairs or jump
Incidental finding on a routine X-ray: no immediate treatment is necessary
Differential diagnosis from IVDD (acute) or degenerative lumbar stenosis (lumbosacral region)

Practical application

Distinguishing Between Spondylosis and IVDD:

Feature	Spondylosis	Intrinsic Vascular Dural Dysplasia
Start	Gradually, over months or years	Acute to subacute (hours to days)
Main symptom	Stiffness, chronic pain	Signs of paralysis (paraparesis/tetraparesis)
Imaging	X-ray is sufficient	MRT für Diagnosis preferred
Age	Mostly older dogs (> 7 years)	Breeds prone to chondrodystrophy: even at a young age
Treatment	Conservative (NSAIDs, physical therapy)	Depending on the severity: conservative or surgical

Conservative management of symptomatic spondylosis: - NSAIDs: Carprofen, Meloxicam, Mavacoxib — by veterinary prescription - Weight management: Maintaining a healthy weight significantly reduces strain on the spine - Physical therapy: mobilization, stretching, strengthening of the paravertebral muscles - Hydrotherapy: underwater treadmill, swimming — low-impact exercise - Orthopedic mattress: soft, joint-friendly sleeping surface

Common Mistakes & Myths

“Spondylosis means the dog will soon be unable to walk.” Spondylosis is usually chronic but stable—complete paralysis is rare. Most dogs with spondylosis remain mobile with proper treatment.
“The bone spurs must be surgically removed.” Surgery is rarely indicated for spondylosis and is only recommended in cases of severe neurological impairment caused by dorsal compression. Conservative management is sufficient in most cases.
“Dogs with spondylosis should not be restricted from exercise.” Regular, controlled exercise (no sudden stops, starts, or jumping) helps maintain the paravertebral muscles and reduces pain. Inactivity increases stiffness and muscle atrophy.

Current State of Research (2026)

Spondylosis deformans is well characterized in veterinary medicine. New imaging modalities (CT, MRI) allow for more precise differentiation between spondylosis, facet joint osteoarthritis, and lumbosacral stenosis. Regenerative therapies (PRP, stem cells) are being investigated for degenerative spinal disorders in dogs. Multimodal pain management (NSAIDs + physical therapy + acupuncture) is the standard conservative treatment.

Frequently Asked Questions

What is spondylosis in dogs?

Deforming spondylosis is the formation of bone spurs (osteophytes) along the edges of the vertebral bodies—a degenerative age-related process affecting the spine. It is often an asymptomatic incidental finding on X-rays. Symptoms include stiffness in the back and chronic back pain, especially after periods of rest.

How does spondylosis differ from a herniated disc?

Spondylosis is a chronic degenerative condition characterized by the formation of bone spurs, causing stiffness and chronic pain. Intervertebral disc disease (IVDD) occurs when disc tissue protrudes into the spinal canal, causing acute to subacute signs of paralysis. An MRI is often necessary for IVDD; an X-ray is sufficient for spondylosis.

How is spondylosis treated in dogs?

Asymptomatic spondylosis does not require treatment. Symptomatic cases: NSAIDs (carprofen, meloxicam), weight control, physical therapy, and hydrotherapy are first-line treatments. Surgery is indicated only in cases of severe neurological impairment caused by dorsal osteophytes.
