Small dogs are often cherished for their lively personalities and compact size, making them ideal companions for many pet owners. However, these smaller breeds can be susceptible to certain health conditions that require special attention and care. One such condition is Intervertebral Disc Disease (IVDD) in dogs. IVDD is a degenerative disease that affects the spinal discs, which serve as cushions between the vertebrae of the spine. This article will explore the nature of IVDD in small dogs, its causes, symptoms, diagnosis, treatment options, and preventive measures.
Understanding IVDD in Dogs

Intervertebral Disc Disease refers to the process where the intervertebral discs lose their elasticity and flexibility over time. In healthy dogs, these discs act as shock absorbers, allowing the spine to bend and flex without causing damage. However, in dogs with IVDD, the discs become brittle and prone to rupture or herniation. When this happens, the disc material can press on the spinal cord, leading to pain, nerve damage, and even paralysis in severe cases.
Small dog breeds, particularly those classified as chondrodystrophic breeds, are at a higher risk of developing IVDD. Chondrodystrophic breeds include Dachshunds, Basset Hounds, Beagles, French Bulldogs, Pekingese, and Shih Tzus. These breeds have an inherent genetic predisposition that leads to early degeneration of the intervertebral discs. Non-chondrodystrophic breeds can also develop IVDD, but it is less common and typically occurs later in life.
Causes of IVDD in Small Dogs
The exact cause of IVDD in dogs remains unclear, but several factors contribute to its development. Genetics plays a significant role, especially in chondrodystrophic breeds. These dogs are born with an abnormal cartilage structure that predisposes them to disc degeneration. Environmental factors, such as obesity, lack of exercise, and repetitive strain on the spine, can exacerbate the condition. Additionally, trauma or injury to the back may trigger a disc rupture in already compromised dogs.
Symptoms of IVDD in Dogs
Recognizing the symptoms of IVDD in dogs is crucial for early intervention and improved outcomes. The clinical signs of IVDD can vary depending on the severity and location of the affected disc. Common symptoms include:
1. Pain: Dogs with IVDD often exhibit signs of pain, such as whining, reluctance to move, or a hunched posture.
2. Weakness or Wobbliness: Affected dogs may have difficulty walking or show uncoordinated movements, especially in the hind legs.
3. Loss of Reflexes: A loss of reflexes in the limbs may indicate pressure on the spinal cord.
4. Paralysis: In severe cases, dogs may become partially or fully paralyzed, unable to move their legs or control their bladder and bowels.
If you notice any of these symptoms in your small dog, it is essential to seek veterinary care immediately. Early diagnosis and treatment can significantly improve the prognosis.
Diagnosing IVDD in Dogs
When a veterinarian suspects IVDD in a dog, they will perform a thorough physical examination and neurological assessment. This involves evaluating the dog's gait, muscle tone, reflexes, and response to touch. Imaging studies are necessary to confirm the diagnosis and locate the affected disc(s). X-rays can help identify abnormalities in the spine, but they cannot visualize soft tissues like discs or the spinal cord. For a more detailed examination, advanced imaging techniques such as myelography, computed tomography (CT), or magnetic resonance imaging (MRI) are used. These methods provide clear images of the spinal cord and surrounding structures, allowing veterinarians to pinpoint the source of the problem.
Treatment Options for IVDD in Dogs
The treatment for IVDD in dogs depends on the severity of the condition and the specific needs of the individual dog. Treatment options generally fall into two categories: conservative management and surgical intervention.
Conservative Management
For mild cases of IVDD, conservative management may be sufficient to alleviate symptoms and prevent further damage. This approach typically includes:
1. Rest and Confinement: Strict rest is critical to allow the inflamed tissues to heal. Dogs should be confined to a crate or small area to limit movement and avoid exacerbating the condition.

2. Pain Management: Veterinarians may prescribe anti-inflammatory medications or pain relievers to reduce discomfort and inflammation.
3. Physical Therapy: Once the acute phase has passed, physical therapy exercises can help restore strength and mobility.
4. Weight Management: Maintaining a healthy weight reduces stress on the spine and minimizes the risk of future episodes.
Surgical Intervention
In severe cases or when conservative management fails, surgery may be necessary to relieve pressure on the spinal cord and remove damaged disc material. Surgical options include hemilaminectomy, dorsal laminectomy, and ventral slot procedures. The choice of surgery depends on the location and extent of the disc damage. While surgery carries risks, it can offer significant relief and improve the quality of life for affected dogs.

Post-Surgical Care
After surgery, dogs require careful post-operative care to ensure proper healing and recovery. This includes strict confinement, regular follow-up visits, and adherence to prescribed medications. Physical rehabilitation exercises under the guidance of a veterinarian or certified canine rehabilitation practitioner can aid in restoring function and preventing complications.
Preventing IVDD in Small Dogs
While not all cases of IVDD in dogs are preventable, there are steps pet owners can take to minimize the risk and manage the condition:
1. Maintain a Healthy Weight: Obesity increases the strain on the spine, so keeping your dog at a healthy weight is vital.
2. Avoid Jumping: Encourage your small dog to use ramps or stairs instead of jumping on and off furniture or into vehicles.
3. Use Harnesses: When walking your dog, use a harness instead of a collar to reduce neck and spine strain.
4. Provide Adequate Exercise: Regular, moderate exercise helps maintain muscle tone and supports spinal health.

5. Monitor for Symptoms: Stay vigilant for early signs of IVDD and seek veterinary care promptly if any symptoms arise.

Living with a Dog with IVDD
Managing a dog with IVDD requires dedication and patience. Many dogs with this condition lead happy, fulfilling lives with appropriate care and adjustments. Owners may need to make modifications to their home environment, such as providing non-slip flooring, elevated food bowls, and comfortable bedding. Mobility aids, such as carts or wheelchairs, can assist dogs with severe mobility impairments.
Emotional Support
Dealing with a dog diagnosed with IVDD can be emotionally challenging for pet owners. It is important to remember that many dogs respond well to treatment and can enjoy a good quality of life. Support groups, both online and in-person, can provide valuable resources and encouragement for those navigating this journey.
Conclusion

IVDD in dogs is a serious condition that primarily affects small, chondrodystrophic breeds. Understanding its causes, recognizing its symptoms, and seeking prompt veterinary care are essential for managing the disease effectively. Through a combination of medical treatment, surgical intervention when necessary, and preventive measures, many dogs with IVDD can live comfortably and happily. By staying informed and proactive, pet owners can help ensure the best possible outcome for their beloved companions.
