What is Intervertebral Disc Disease (IVDD)?

Intervertebral Disc Disease, commonly known as IVDD, is a serious condition that affects a significant number of dogs, particularly as they age. To fully grasp the impact of this disease, it’s essential to understand the basic anatomy of a dog’s spine and the role of intervertebral discs.

The Canine Spine and Intervertebral Discs

The spine is a complex structure made up of numerous vertebrae, which are small bones forming the backbone. Between each pair of vertebrae lies an intervertebral disc, which acts as a cushion and provides flexibility to the spine. These discs are composed of a tough outer layer called the annulus fibrosus and a gel-like center known as the nucleus pulposus. In a healthy dog, these discs enable a range of movements and absorb shocks during physical activities.

Types of IVDD: Hansen Type I and Type II

IVDD in dogs is categorized into two main types based on the pathology of the disc degeneration:

1. Hansen Type I: This type is more common in smaller, chondrodystrophic breeds like Dachshunds, Beagles, and Shih Tzus. These breeds have a genetic predisposition to early disc degeneration. In Hansen Type I, the disc material hardens and then suddenly or gradually ruptures, causing the disc material to protrude into the spinal canal.
2. Hansen Type II: Larger, non-chondrodystrophic breeds, such as Labrador Retrievers and German Shepherds, are more prone to this type. In Hansen Type II, the degeneration process is slower, involving a gradual bulging of the disc into the spinal canal over a longer period.

The Impact of IVDD

When a disc material herniates or bulges, it can compress the spinal cord and nerves, causing pain, nerve damage, and in severe cases, paralysis. The severity of symptoms depends on the location and extent of the spinal cord compression. IVDD can occur in any part of the spine, but the most common areas are the neck (cervical spine) and near the back of the rib cage (thoracolumbar spine).

Understanding IVDD is the first step in recognizing its signs and preparing for effective treatment and management. In the following sections, we will delve into the causes, symptoms, and treatment options for this complex and challenging condition.

Causes and Risk Factors of IVDD in Dogs

Intervertebral Disc Disease in dogs doesn’t occur randomly; certain factors increase the risk of a dog developing this condition. Understanding these can help dog owners take preventive measures and be vigilant about early signs of IVDD.

Genetic Predisposition

• Breed-Specific Risk: Some dog breeds are more susceptible to IVDD, primarily due to genetic factors. Breeds with short legs and long backs, like Dachshunds, Basset Hounds, and Corgis, are especially prone to Hansen Type I IVDD. This is due to a condition called chondrodystrophy, where the development of cartilage and bone is altered, leading to early degeneration of intervertebral discs.
• Hereditary Factors: Even in non-chondrodystrophic breeds, genetics can play a role. Dogs with a family history of IVDD are at a higher risk.

Age-Related Degeneration

• Aging Spine: As dogs age, their intervertebral discs naturally degenerate and lose elasticity, making older dogs more susceptible to disc herniation, especially in the case of Hansen Type II IVDD.
• Early Onset in Certain Breeds: While IVDD is generally a disease of middle-aged to older dogs, in breeds predisposed to chondrodystrophy, symptoms can appear as early as three to six years of age.

Lifestyle Factors

• Physical Activity: Sudden, intense activities or repetitive strain can lead to disc injuries in dogs. Activities like jumping from heights, playing rough, or intense agility training can increase the risk of IVDD, particularly in predisposed breeds.
• Obesity: Overweight dogs are at a higher risk for IVDD. Excess weight puts additional stress on the spine and discs, exacerbating the degeneration process.
• Improper Handling: Lifting a dog incorrectly, such as by the front or back legs, can cause undue stress on the spine, leading to disc damage.

Nutritional Factors

• Diet: Nutrition plays a role in overall spinal health. A balanced diet rich in essential nutrients is important for maintaining healthy discs and bone structure.

Environmental Factors

• Living Conditions: Dogs that live primarily outdoors in harsh conditions or those without proper bedding may also have an increased risk due to continuous minor trauma or lack of support to the spine.

While not all cases of IVDD can be prevented, understanding these risk factors is crucial for early intervention and management. In the following sections, we will explore the symptoms of IVDD, how it is diagnosed, and the available treatment options.

Symptoms of IVDD in Dogs

Recognizing the symptoms of Intervertebral Disc Disease (IVDD) in dogs is key to timely and effective treatment. The symptoms can range from mild discomfort to severe pain and paralysis, depending on the location and severity of the disc herniation.

Early Signs to Watch For

• Pain and Discomfort: One of the first signs of IVDD is pain in the neck or back. This may manifest as reluctance to move, yelping when touched, a hunched back, or neck stiffness.
• Changes in Gait or Posture: Dogs with IVDD might show an unsteady walk, weakness in the limbs, or a noticeable change in posture, such as a lowered head stance in cases of neck disc herniation.

Progression of Symptoms

• Reduced Activity and Lethargy: As the condition progresses, dogs may become less active, avoid jumping or climbing stairs, and seem lethargic.
• Loss of Bladder and Bowel Control: In severe cases, dogs may lose control over their bladder and bowels due to nerve damage.
• Paralysis: Partial or complete paralysis can occur if the spinal cord is significantly compressed. This is a medical emergency requiring immediate veterinary attention.

Symptoms Based on Affected Area

• Cervical (Neck) IVDD: When the neck area is affected, dogs might show reluctance to move their head, neck pain, and front limb weakness.
• Thoracolumbar (Mid-Back) IVDD: This is more common and typically presents as back pain, rear limb weakness, and in severe cases, paralysis of the hind legs.

Behavioral Changes

• Anxiety or Depression: Dogs in pain may exhibit changes in behavior, such as increased anxiety, aggression when touched, or signs of depression.

Varying Severity of Symptoms

• Intermittent Symptoms: In some cases, symptoms may appear intermittently, worsening during periods of activity and improving with rest.

It’s important to note that these symptoms are not exclusive to IVDD and can be indicative of other health issues. If you observe any of these signs in your dog, a prompt visit to the vet is crucial for proper diagnosis and treatment. In the next section, we will delve into how IVDD is diagnosed and the various imaging techniques used in its detection.

Diagnosing IVDD in Dogs

Accurate diagnosis of Intervertebral Disc Disease (IVDD) in dogs is critical for determining the most effective treatment plan. Veterinarians use a combination of clinical examination, patient history, and advanced imaging techniques to diagnose IVDD.

Veterinary Examination Procedures

• Clinical Examination: The vet will start with a thorough physical and neurological examination. This includes assessing the dog’s gait, reflexes, pain response, and muscle strength.
• Medical History: A detailed medical history helps the veterinarian understand any previous incidents of pain or injury, breed predisposition, and the progression of current symptoms.

Imaging Techniques

• X-rays (Radiographs): While X-rays cannot show the discs themselves, they can reveal changes in the space between vertebrae, signs of spinal cord compression, or calcified discs, which are indicative of IVDD.
• Magnetic Resonance Imaging (MRI): MRI is the gold standard for diagnosing IVDD as it provides detailed images of the spinal cord, intervertebral discs, and surrounding soft tissues.
• Computed Tomography (CT) Scan: CT scans are useful for providing a more detailed view of the vertebral bones and can be used in conjunction with MRI to diagnose IVDD.

Differential Diagnosis

• Ruling Out Other Conditions: It’s important to differentiate IVDD from other conditions that can cause similar symptoms, such as spinal tumors, infections, or injuries.

Invasive Diagnostic Procedures

In some cases, more invasive procedures like a myelogram, where dye is injected around the spinal cord and then imaged, might be necessary. However, with the advancements in MRI, the use of myelograms has decreased significantly.

The diagnosis of IVDD is a crucial step that guides the course of treatment. Early and accurate diagnosis can significantly improve the chances of a successful recovery. After diagnosing IVDD, the next step is to evaluate the severity of the condition and determine the most appropriate treatment plan, which may include conservative management, surgical intervention, or a combination of both. We will explore these treatment options in the following sections.

Treatment Options for IVDD in Dogs

Once a diagnosis of Intervertebral Disc Disease (IVDD) is confirmed, the treatment approach is determined based on the severity of the condition, the location of the disc herniation, and the dog’s overall health. Treatment for IVDD in dogs typically falls into two categories: conservative management and surgical intervention.

Conservative Management

• Rest and Confinement: Strict rest is crucial for recovery. This often involves confining the dog to a small space, like a crate, to limit movement and prevent further spinal cord damage.
• Medications: Anti-inflammatory drugs, pain relievers, and muscle relaxants are commonly prescribed to reduce inflammation, alleviate pain, and improve mobility.
• Physical Rehabilitation: After the initial rest period, physical therapy, including controlled exercises, hydrotherapy, and massage, can be beneficial in regaining strength and mobility.

Surgical Treatments

• Indications for Surgery: Surgery is typically recommended in cases where there is severe spinal cord compression, persistent pain, or when conservative treatment has failed. It’s also the primary option for dogs experiencing paralysis or severe neurological deficits.
• Types of Surgical Procedures:
  • Hemilaminectomy: This is the most common surgery for IVDD, where part of the vertebra is removed to access and remove the herniated disc material.
  • Dorsal Laminectomy: Used primarily for discs herniating upwards or for cervical (neck) disc problems.
  • Disc Fenestration: Sometimes performed alongside other surgeries, this involves removing the nucleus of the disc to prevent future herniation.

Rehabilitation and Physical Therapy

• Post-Surgical Care: Rehabilitation is vital after surgery to aid recovery. It may include physiotherapy, hydrotherapy, and pain management strategies.
• Ongoing Management: Consistent follow-up and a tailored rehabilitation plan are crucial for long-term recovery and preventing recurrence.

Alternative Therapies

• Acupuncture and Laser Therapy: These can be used as adjunct therapies to reduce pain and inflammation and promote healing.

It’s important to note that the choice between conservative management and surgery depends on various factors, including the dog’s specific circumstances and the veterinarian’s recommendation. Regardless of the treatment path chosen, a commitment to the dog’s long-term health and comfort is paramount. Up next, we will discuss how to manage and care for a dog living with IVDD, focusing on home care, diet, exercise, and overall wellbeing.
