Intervertebral disc disease represents the most common cause of spinal cord injury in dogs and can occasionally occur in cats.
Intervertebral Disc Disease (IVDD) is a broad term, widely used by veterinary clinicians, referring to disc degeneration and clinical neurological disease due to disc herniation.
IVDD can lead to Intervertebral disc herniation which consists of the displacement of the Intervertebral Disc (IVD) from its physiological site leading to spinal cord compression and causing severe inflammation and pain.
The IVD is a cylinder-shaped structure that lies between adjacent surfaces of the vertebrae. All the IVDs consist of three different anatomical parts: the outer annulus fibrosus, the central nucleus pulposus, and the cartilage end-plate that anchor the disc cranially and caudally to the adjacent vertebral bone. The dynamic interplay of these portions is responsible of the unique functional property of intervertebral discs. They act as viscoelastic hydrodynamic cushions absorbing shocks and providing spinal flexibility.
IVD herniation typically occurs following disc degeneration, although, in rare cases, exogenous trauma can be implicated as well, resulting in the herniation of a non-degenerative IVD.
Disc herniation has been sub-classified as a disc extrusion or Hansen type I, and a disc protrusion or Hansen type II, based on morphology, gross pathology and MRI. Differentiating these subtypes of IVD herniation may lead to different treatment recommendations and outcomes.
Disc extrusion (Hansen type I) is a type of disc herniation associated with a defect in all layers of the annulus fibrosus which allows displacement of the degenerative nucleus pulposus into the vertebral canal.
It occurs when the disc is no longer able to act as a shock absorber or help with the weight load put on the spine. This happens when the disc undergoes degenerative processes that make it dehydrated. When the IVD degenerates, even normal movements such as jumping or twisting can lead to acute disc herniation. The onset of clinical signs is usually acute.
This process can be age-related but there are certain predisposed breeds that can suffer disc problems from when they are young adult dogs.
These breeds are referred as ‘chondrodystrophic’ and are characterized by having disproportionably short and curved limbs, such as:
Although the majority of the dogs above are small to medium breeds, larger breeds can also be affected.
A Disc Protrusion (Hansen type II) is more similar to human disc disease and consists of a slow protrusion of the disc into the vertebral canal.) It occurs when a rupture affects the inner layers of the annulus fibrosus while the outer layers remain intact and bulging. This event leads to partial displacement of the nucleus pulposus into the disrupted annulus fibrosus.
The onset is usually chronic, with developing clinical signs in weeks to months. This type of IVDD is more common in large non- chondrodystrophic breeds such as German shepherd and Labrador retriever.
The severity of clinical signs may vary from pain only to severe neurologic dysfunction, as detailed in the following scale:
This grading system is of help in describing the degree of injury; however, as a prognostic indicator, the most significant factor is the presence or absence of deep pain sensation.

The first step of almost any diagnostic protocol is the signalment, the collection of a thorough history and a complete physical examination. In the investigation of the patient with suspected IVD herniation, a complete neurological examination is carried out with the aims to localise the lesion to specific spinal cord segments and to determinate its severity.
Spinal radiographs may reveal characteristic changes of disc disease such as calcified disc material within the vertebral canal or narrowing of the IVD space or the foramen, however, radiographs rarely provide the accurate conformation and localisation required for surgical management.
For a definitive diagnosis it is necessary to demonstrate spinal cord compression, which can be obtained by CT or MRI. Patients must lie completely still for their scan and this is only possible with the use of sedation (for CT) or general anaesthesia (for MRI).
Conservative treatment may be considered in grade I and II cases, although the recovery period is significantly shorter with surgical treatment. In grades II to V the surgical treatment increases the success rate and should be considered. It’s important to note that for Grade V cases surgery should be performed within 48hours of the first clinical signs, after which the prognosis worsens.

Quick answers for vets and pet owners about referrals, services, and what to expect.
Yes. Most of our procedures are covered by pet insurance policies. We provide a detailed, itemised invoice for every case, which makes the claims process straightforward. We can also assist with pre-authorisation requests. Please bring your insurance details to your appointment, or contact us in advance if you need guidance.
We provide a full, itemised written estimate before any procedure begins. The price in that estimate is the price you pay, it doesn’t change once approved. We’re one of the only referral centres in the UK to operate this way, and we’ve done so since 2008. No hidden fees, no end-of-treatment surprises.
No. While the majority of our cases come via veterinary referral, we welcome self-referring pet owners directly. You can book a consultation through our website. If you’re self-referring, it’s helpful to bring any recent vet notes or clinical history with you.
Complete our online referral form which takes under 5 minutes. You can also refer via our dedicated WhatsApp service by scanning the QR code on our contact page.
