IVDD in Dogs
IVDD, short for Intervertebral Disc Disease, is a condition that primarily affects the intervertebral discs of the spine. In dogs with IVDD, these discs degenerate or become damaged, leading to a range of neurological symptoms.
Por Dr. Isabella Miao
Intervertebral Disc Disease (IVDD) is a common and potentially debilitating condition that affects many dogs, particularly those with long backs or short legs. While IVDD can be a source of pain and discomfort for our furry friends, early detection and appropriate management can greatly improve their quality of life. In this article, we will delve into the causes, symptoms, diagnosis, and treatment options for IVDD in dogs.
What is IVDD in Dogs?
IVDD, short for Intervertebral Disc Disease, is a condition that primarily affects the intervertebral discs of the spine. These discs act as cushions or shock absorbers between the vertebrae, providing flexibility and support to the spine. In dogs with IVDD, these discs degenerate or become damaged, leading to a range of neurological symptoms.
How Common is IVDD in Dogs
IVDD tends to be more frequently observed in specific dog breeds, particularly those characterized by long torsos and short legs. Breeds such as Dachshunds, Corgis, Beagles, Pekingese, Shih Tzus, and French Bulldogs are recognized for their heightened susceptibility to IVDD. In these particular breeds, the incidence of this condition can be notably elevated. While pinpointing an exact percentage for the overall occurrence of IVDD is a challenging task, it is estimated that a substantial proportion of dogs, particularly those belonging to these predisposed breeds, may encounter IVDD at some point in their lives. For instance, estimates indicate that as many as 25% of Dachshunds may develop IVDD during their lifetime.
What Causes IVDD in Dogs?
Genetics: Certain breeds, such as Dachshunds, Corgis, and Beagles, are genetically predisposed to IVDD due to their long backs and short legs.
Aging: Like in humans, the intervertebral discs naturally degenerate with age, making older dogs more susceptible to IVDD.
Trauma: In some cases, trauma or injury to the spine can cause immediate disc herniation or accelerate degeneration.
Obesity: Excessive weight puts additional stress on the spine, increasing the risk of disc problems.
What are the Stage of IVDD?
Intervertebral Disc Disease (IVDD) in dogs is typically categorized into four stages, ranging from mild to severe. These stages help veterinarians assess the severity of the condition and determine the appropriate treatment. Here's an overview of each stage:
Stage 1 IVDD (Mild)
In the early stage of IVDD, the intervertebral disc may be bulging or starting to degenerate, but it has not yet herniated or caused significant compression of the spinal cord.
Dogs in Stage 1 may exhibit mild signs of discomfort, such as stiffness or pain, but they can still walk and move relatively normally.
With proper rest, anti-inflammatory medication, and conservative management, many dogs with Stage 1 IVDD can recover without the need for surgery.
Stage 2 IVDD (Moderate)
In Stage 2, the intervertebral disc has herniated or partially ruptured, causing some compression of the spinal cord.
Dogs in this stage may experience more pronounced pain, weakness in one or more limbs, and difficulty walking. They may have a wobbly or unsteady gait.
Treatment options for Stage 2 IVDD may include medical management with pain medication, anti-inflammatories, and strict rest. Surgery may also be considered, depending on the severity and response to conservative treatment.
Stage 3 IVDD (Severe)
Stage 3 IVDD is characterized by a complete disc herniation that severely compresses the spinal cord.
Dogs in this stage may experience paralysis in one or more limbs, loss of bladder and bowel control, and intense pain.
Emergency surgery is often required to decompress the spinal cord and relieve the pressure. The prognosis varies depending on the duration and severity of compression.
Stage 4 IVDD (End-Stage)
Stage 4 IVDD represents the most advanced and often irreversible stage of the disease.
In this stage, there is severe spinal cord damage, and dogs may be completely paralyzed in the affected area. They may also lose sensation in the limbs.
While surgery may still be considered to stabilize the spine, recovery of function in Stage 4 IVDD is less likely, and dogs may require ongoing supportive care and physical therapy to maintain their quality of life.
How to Diagnose IVDD in Dogs?
While X-rays can help identify changes in the spine, they are often less informative in diagnosing IVDD compared to other imaging methods. However, they can rule out other causes of spinal pain.
Advanced imaging is required to allow a definitive diagnosis. Magnetic Resonance Imaging (MRI) or Computed Tomography (CT) scans provide detailed images of the spinal cord and intervertebral discs. These imaging techniques are highly effective in diagnosing IVDD and pinpointing the exact location of disc herniation or compression.
In some cases, a CSF tap or analysis of cerebrospinal fluid may be performed to rule out other neurological conditions or infections that can mimic IVDD symptoms.
Once the diagnosis of IVDD is confirmed, the veterinarian can determine the severity of the condition and recommend an appropriate treatment plan. The choice of treatment (conservative management, surgery, or a combination of both) will depend on factors such as the stage of IVDD, the location of the disc herniation, and the overall health of the dog.
How Long Does Spinal Surgery for Disc Disease Take?
The duration of spinal surgery for disc disease can vary significantly depending on several factors, including the type of procedure being performed, the number of affected discs, the patient's overall health, and the surgeon's experience. Here are some general guidelines for different types of spinal surgeries for disc disease:
Discectomy: This is a relatively common and often minimally invasive procedure. It can typically take anywhere from 30 minutes to 2 hours, depending on the complexity and the number of discs involved.
Microdiscectomy: A microdiscectomy is a minimally invasive form of discectomy that uses a small incision and specialized instruments. This procedure is usually shorter in duration, typically taking around 1 to 1.5 hours.
Spinal Fusion: Spinal fusion surgery is a more extensive procedure that involves fusing two or more vertebrae to stabilize the spine. This type of surgery can take several hours, typically ranging from 2 to 6 hours or more, depending on the complexity.
For Mild Ones, What Medicines Can Be Used to Treat Effectively?
For mild cases of disc disease, various medications may be used to manage symptoms and help alleviate pain and inflammation. Common medications that may be used for mild disc disease include:
Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): NSAIDs, such as meloxicam, ibuprofen or naproxen, can help reduce pain and inflammation associated with disc disease. These medications are available over the counter or in prescription strength.
Acetaminophen: Acetaminophen (Tylenol) can be effective in managing mild to moderate pain. It is available over the counter and is generally considered safe when used as directed.
Muscle Relaxants: Muscle relaxant medications, like cyclobenzaprine (Flexeril) or methocarbamol (Robaxin), may be prescribed to relieve muscle spasms and improve comfort.
Oral Steroids: In some cases, a short course of oral steroids (e.g., prednisone) may be prescribed to reduce inflammation and pain associated with disc disease.
Topical Analgesics: Over-the-counter topical creams or ointments containing ingredients like capsaicin or menthol can be applied directly to the skin over the affected area to provide localized pain relief.
Nerve Pain Medications: If nerve compression is a significant issue, medications like gabapentin (Neurontin) or pregabalin (Lyrica) may be prescribed to manage nerve pain and discomfort.
Opioid Medications (if necessary): In some cases, when pain is severe and not adequately controlled by other medications, healthcare providers may prescribe opioid medications. However, these are typically used cautiously due to the risk of dependence and side effects, and they are generally not the first choice for mild cases.
Can IVDD in Dogs Be Cured?
Intervertebral Disc Disease (IVDD) in dogs is typically not considered curable, but it can often be managed and treated to improve a dog's quality of life and reduce pain and discomfort.
How Long Before My Paralysed Dog Will Walk Again?
Common causes of paralysis in dogs include intervertebral disc disease (IVDD), spinal cord injuries, degenerative myelopathy, and certain neurological conditions. The prognosis for recovery varies with each condition:
Intervertebral Disc Disease (IVDD): If your dog has IVDD and undergoes surgery or receives appropriate medical treatment promptly, there's a chance for a significant improvement in their condition. Some dogs can regain the ability to walk within a few days to weeks after surgery, while others may take longer. Physical therapy and rehabilitation can also play a crucial role in recovery.
Spinal Cord Injuries: The recovery from spinal cord injuries depends on the severity and location of the injury. Some dogs may regain partial or full mobility with intensive medical treatment, physical therapy, and time. The recovery process can span from weeks to months.
Degenerative Myelopathy: This is a progressive condition with no cure, and dogs with degenerative myelopathy will typically experience a gradual loss of mobility over time. While there's no guarantee of regaining full mobility, physical therapy and assistive devices can help improve their quality of life and maintain some level of mobility for a period.
Prevention
While IVDD cannot always be prevented, there are steps you can take to reduce the risk:
Maintain a healthy weight: Keep your dog at a healthy weight to reduce stress on their spine.
Regular exercise: Encourage regular, low-impact exercise to keep your dog's muscles strong and maintain flexibility.
Proper handling: Be cautious when lifting or supporting your dog, especially if they are prone to back problems.
Supplements for IVDD in Dogs
The appropriate supplements may vary depending on the stage and severity of IVDD in your dog. Here are some supplements that are sometimes considered:
Omega-3 Fatty Acids: Omega-3 fatty acids, often found in fish oil supplements, have anti-inflammatory properties and can help reduce inflammation and support joint health. They may help alleviate some symptoms of IVDD.
Glucosamine and Chondroitin: These supplements are often used to support joint health and may be beneficial for dogs with IVDD, especially if they have associated joint problems.
Turmeric (Curcumin): Turmeric is known for its anti-inflammatory properties. Curcumin, the active compound in turmeric, may help reduce inflammation and pain in dogs with IVDD.
Antioxidants: Antioxidants like vitamins C and E can help neutralize free radicals and reduce oxidative stress, which can be beneficial for dogs with spinal issues.
Methylsulfonylmethane (MSM): MSM is a sulfur compound that is sometimes used to support joint health and reduce inflammation.
B-complex vitamins: B vitamins can play a role in nerve function and overall health. A deficiency in certain B vitamins may affect nerve health.
CBD (Cannabidiol): Some pet owners have reported improvements in pain and mobility in dogs with IVDD when using CBD products. However, the use of CBD should be discussed with a veterinarian to ensure safety and appropriate dosing.
Probiotics: A healthy gut can contribute to overall health and immune function. Probiotic supplements may help maintain gut health, which is important for dogs with IVDD.
Green-Lipped Mussel Extract: This supplement is rich in omega-3 fatty acids and is believed to have anti-inflammatory properties. It's sometimes used to support joint health in dogs.
Herbal Supplements: Certain herbs like Boswellia and yucca are believed to have anti-inflammatory properties and can be considered for dogs with IVDD.
How to Keep Your Dog's Weight?
Calculating the daily calorie needs for your dog based on their weight is an important step in ensuring they receive the appropriate amount of food to maintain a healthy weight. Here's a general guideline to estimate your dog's daily calorie needs:
Determine Your Dog's Resting Energy Requirement (RER):
The Resting Energy Requirement is the number of calories your dog needs to maintain basic bodily functions when at rest. It can be calculated using the following formula:
RER = 70 x (weight in kilograms) ^ 0.75
To convert your dog's weight from pounds to kilograms, divide the weight by 2.2.
For example, if your dog weighs 20 pounds (9.07 kilograms):
RER = 70 x (9.07 ^ 0.75) = 318.77 calories per day
Adjust for Activity Level:
The RER provides the baseline number of calories your dog needs to maintain its current weight. To determine the total daily calorie requirement, you'll need to adjust this number based on your dog's activity level:
Sedentary (little to no exercise): Multiply the RER by 1.2.
Lightly active (light exercise or play): Multiply the RER by 1.4 to 1.6.
Moderately active (regular exercise or daily walks): Multiply the RER by 1.6 to 1.8.
Very active (high-intensity exercise or working dogs): Multiply the RER by 1.8 to 2.0 or more.
Choose the appropriate activity multiplier based on your dog's daily physical activity level.
Multiply the RER by the activity multiplier you selected to find your dog's estimated total daily calorie needs:
Total Daily Calories = RER x Activity Multiplier
Conclusion
IVDD in dogs can be a challenging condition, but with prompt diagnosis and appropriate treatment, many dogs can regain their mobility and lead happy lives. If you suspect your dog may have IVDD, don't hesitate to consult your veterinarian for a proper evaluation and guidance on the best course of action. Remember, early intervention is key to managing this condition effectively and ensuring the best possible outcome for your beloved pet.
