Ivdd in dogs is a serious condition that affects the spine, causing a range of symptoms from mild discomfort to paralysis.
The spine is made up of vertebrae that are stacked on top of each other, with a soft cushioning disc between each one.
Some breeds are more prone to ivdd due to their physical characteristics, such as the basset hound and dachshund, which have long bodies and short legs.
Life expectancy for dogs with ivdd varies depending on the severity of the condition, with some dogs living up to 10 years or more with proper care and management.

What Is IVDD?
IVDD is a condition that affects the spine of dogs, causing compression or rupture of the spinal cord. This can lead to pain, weakness, and loss of coordination.
The condition is often related to the dog's weight, with breeds that are prone to obesity being at higher risk. The weight can put additional pressure on the spine, leading to the compression or rupture.

Some breeds are more susceptible to IVDD due to their body structure, such as the Dachshund, Basset Hound, and Beagle. These breeds have a long, narrow spine that can be prone to injury.
The symptoms of IVDD can vary depending on the severity of the condition, but may include sudden paralysis, loss of feeling in the legs, and pain when moving.
Causes and Risk Factors
Intervertebral disc disease (IVDD) in dogs is a common condition that affects many breeds.
The condition is often caused by a combination of genetics and body shape.
Dachshunds, Basset Hounds, and Corgis are among the breeds most prone to IVDD due to their long, narrow spines.
Annpe
Annpe is a type of genetic disorder that affects the body's ability to break down certain amino acids, leading to an accumulation of these substances in the blood and urine.
Research suggests that Annpe is caused by a deficiency of the enzyme responsible for breaking down the amino acid phenylalanine, which is found in high levels in certain foods such as chocolate and nuts.
This enzyme deficiency can lead to a buildup of phenylalanine in the body, causing a range of symptoms including intellectual disability, seizures, and behavioral problems.
Annpe can be inherited in an autosomal recessive pattern, meaning that a person must inherit two copies of the mutated gene (one from each parent) to develop the disorder.
In some cases, Annpe can also be caused by a mutation in the gene that codes for the enzyme responsible for breaking down phenylalanine.
If left untreated, Annpe can lead to serious health complications, including brain damage and intellectual disability.
At Risk
Dogs with IVDD are at risk of having more problems down the road.
Having a history of IVDD can increase the likelihood of future problems, such as worsening disc disease or neurological issues.
Symptoms and Diagnosis
IVDD can affect any dog breed, but some breeds are more prone to it. Dachshunds, Shih Tzus, Beagles, French Bulldogs, and Pekingese are at a higher risk. If your vet suspects IVDD, they will start with a physical exam to check your dog's orthopedic and neurologic condition.
IVDD can cause a range of symptoms, from mild discomfort to paralysis. These can include abnormal walking, hesitation to climb stairs, limping, dragging paws, neck or back pain, and reduced activity level. If you notice any of these symptoms, consult your vet immediately.
The severity of IVDD can be graded from I to V, with grade I involving pain and grade V involving complete paralysis. Your vet may use x-rays, a neurological exam, MRI, or CT scans to diagnose IVDD and determine its severity.
Nucleus Pulposus Extrusion
The nucleus pulposus is a gelatinous, bean-shaped mass that sits within the intervertebral disc. It's made up of a high-water content, up to 88% in young animals, and is derived from the notochord.
The nucleus pulposus is bounded by the transitional zone and lies close to the cartilaginous endplates. Islands of physaliferous notochordal cells can be seen within the ground substance in young animals and are gradually replaced by chondrocyte-like cells with age.
The nucleus pulposus produces low levels of type 2 collagen and proteoglycans, which are highly polarized and create space within the proteoglycan units. This results in extremely large, highly charged complexes that exert a high osmotic pressure, retaining water within the nucleus.
The network of type 2 collagen within the nucleus pulposus is associated with the glycosaminoglycan side chains, lending stability in the face of compressive forces. This is crucial for the overall health and function of the intervertebral disc.
In cases of nucleus pulposus extrusion, the gelatinous mass can be displaced into the vertebral canal, causing compression of the spinal cord and nerve roots. This can lead to a range of clinical signs, including muscle spasms, tense belly, and weakness in the hind legs.
Here are some common symptoms of nucleus pulposus extrusion:
- Muscle spasms
- Tense belly
- Weakness in hind legs
- Crossing back legs when walking
- Inability to walk normally
- Knuckling of back paws, or dragging rear legs
- Inability to support their own weight
- Unable to move or feel back legs
It's worth noting that the symptoms of nucleus pulposus extrusion can vary depending on the location and severity of the extrusion.
Hansen Type II Protrusion
Hansen Type II Protrusion is a type of intervertebral disc herniation. This condition involves the localized displacement of part of the intervertebral disc into the vertebral canal.
The symptoms of Hansen Type II Protrusion can be quite specific. In fact, dogs with this condition may exhibit pain and difficulty jumping.
A key diagnostic feature of Hansen Type II Protrusion is the localized displacement of the intervertebral disc. This is consistent with the majority of veterinary and human literature on the subject.
To better understand the symptoms of Hansen Type II Protrusion, let's take a look at the following table:
Clinical Presentation and Diagnosis
IVD extrusion can occur in any dog breed, but young to middle-aged chondrodystrophic breeds are most commonly affected.
The extruded material can cause a variable degree of spinal cord contusion and compression, as well as compression of nerve roots and inflammation.
An extrusion can occur anywhere along the vertebral column, but it's more common between the T11-12 and L2-3 IVDs.
Clinical signs can range from mild discomfort with no neurological deficits to paralysis of the affected limbs with loss of pain perception.
The typical clinical presentation is an acute onset, painful, and progressive myelopathy.
Diagnosis of IVD extrusion has evolved, and it's now mostly commonly achieved using computed tomography (CT) or MRI.
Both imaging modalities have been shown to be superior to techniques such as plain radiographs and myelography in diagnosing and localizing IVD extrusions.
MRI has the benefit of allowing evaluation of soft tissues such as the spinal cord and intervertebral disks.
The following breeds are predisposed to IVDD:
- Dachshund (45-70% of IVDD cases)
- Shih Tzu
- Beagle
- French bulldog
- Pekingese
IVDD can be graded by severity, with grade I involving pain, grade II, unsteadiness, grade III, weakness, grade IV, paralysis with deep pain, and grade V, complete paralysis with loss of deep pain.
Treatment Options
Dogs with IVDD can be managed with pain meds, muscle relaxants, and strict rest for up to a month. This approach is often combined with physical therapy or laser treatments.
Depending on the duration of neurological deficits and amount of pain, surgery may be recommended for dogs with grades II, III, and IV intervertebral disc disease. The sooner surgery is performed, the better the chances of recovery.
Acupuncture is another treatment option for IVDD, with electroacupuncture (EAP) showing promising results in studies. EAP combined with a standard Western medical approach can help dogs recover more quickly.
If surgery is not recommended, non-invasive treatments like pain medication and strict exercise confinement can be effective in the early stages of IVDD. However, these patients may require surgery further down the road if their condition continues to deteriorate.
Three critical components of non-invasive treatment for IVDD are strict crate rest, sedatives to promote relaxation, and pain medication. Crate rest is mandatory for the IVDD to heal.
Anti-inflammatory medications, such as steroids and anti-inflammatory medications, can be prescribed to help reduce pain and swelling in dogs with mild to moderate IVDD injuries. This is often combined with reduced activity for approximately 4-6 weeks.
Recovery from IVDD surgery requires 6-8 weeks of restricted activity, during which time running, climbing stairs, playing with other dogs, or jumping on furniture should be avoided.
Recovery and Prognosis
Recovery from Intervertebral Disc Disease (IVDD) in dogs can be a long and challenging process.
Some dogs can recover from IVDD without surgery, thanks to medication, back bracing, canine rehab, and animal chiropractic.
If your dog's condition is severe or they're unable to use one or more legs, it's essential to consult with a veterinary surgeon or neurologist.
Recovery time varies depending on the severity of the disease and response to treatment, but some dogs can live a full life after being diagnosed with IVDD.
Crate rest is a crucial component of non-invasive treatment for IVDD, and it's often mandatory for the condition to heal.
Pain medications may also be prescribed to manage discomfort, and surgery is typically recommended for more severe cases where rest and medication are not sufficient.
Recovery from IVDD surgery requires 6 - 8 weeks of restricted activity to allow the spine to heal.

Degenerative Disease Life Expectancy
Some dogs can live a full life after being diagnosed with IVDD, depending on the severity of the disease and response to treatment. Degenerative disc disease can significantly impact a dog's quality of life, but it's not a guarantee of a shortened lifespan. The severity of the disease plays a crucial role in determining life expectancy.

Can a Recover?
Some dogs can live a full life after being diagnosed with IVDD, depending on the severity of the disease and response to treatment.
Dogs with mild symptoms of IVDD in its early stages may be able to recover without surgery, but strict crate rest, sedatives, and pain medication are often necessary to prevent further damage.
If surgery is not the best path forward, pain medication will likely be required to keep the pain manageable while the injury heals. Pain medications can be prescribed if your dog is in discomfort.
Surgery is typically recommended for dogs suffering from more severe cases of IVDD where rest and medication are not sufficient to reduce pain and other symptoms. Surgery outcomes are most successful in dogs that have not lost their ability to walk.
IVDD surgery's success rate is high, with a 90% chance of a full recovery for patients with symptoms graded 1-4 on the scale. However, the success rate plummets to 50% or 60% for grade 5 cases of IVDD, even with prompt surgery.

IVDD can cause life-threatening problems in advanced stages and can be fatal, so prompt treatment is essential. If your dog's surgery is not successful in returning your pet to normal mobility, a dog wheelchair can help your pup to enjoy a happy and active life while living with Intervertebral Disc Disease.
Dogs that recover from IVDD without surgery often require non-invasive treatments like pain medication, Back Bracing, Canine Rehab, and Animal Chiropractic. With the right treatment, some dogs can recover from IVDD without surgery.
Recovery from IVDD surgery requires 6-8 weeks of restricted activity, during which time running, climbing stairs, playing with other dogs, or jumping on furniture need to be prevented in order to avoid further damage as your dog's spine heals.
IVDD can be managed with medication, PEMF Treatment, Strength Training, Spinal Support, and Surgery if needed.
