A disc prolapseProlapse refers to the falling out or protrusion of an organ or part of it from its normal position, often through an opening. In animals, this can include, for example, a rectal mucosal prolapse or a vaginal prolapse., also known as a herniated disc, is a condition in which the soft tissue within a spinal disc protrudes and presses on the surrounding nerves, which can lead to pain and neurological deficits in dogs.

The most important facts at a glance

A herniated disc in dogs occurs when the intervertebral discs, which serve as shock absorbers between the vertebrae, degenerate and the inner core escapes. This often happens in older dogs or certain breeds like Dachshunds, who are genetically more susceptible. Symptoms range from uncoordinated movement and back pain to paralysisParalysis is the complete loss of muscle activity in one or more areas of the body, which can lead to immobility and loss of sensation. Paralysis can be caused by injuries, illnesses, or disorders of the nervous system. and incontinenceIncontinence refers to the inability to voluntarily control urine or stool, leading to involuntary loss. There are various forms, including urinary incontinence and fecal incontinence, which can be caused by different factors..

Causes

Intervertebral discs are flexible structures located between the vertebral bones of the spine. They consist of an outer fibrous ring, the annulus fibrosus, and an inner, gel-like core, the nucleus pulposus. This structure allows the spine to absorb shocks and ensure mobility.

The main cause of a herniated disc in dogs is the degeneration process of the intervertebral discs, which often occurs in older dogs or certain dog breeds. During degeneration, the disc loses elasticity and can tear, allowing the nucleus pulposus to escape.

Genetic factors play a significant role, especially in dog breeds with long backs and short legs, such as Dachshunds and Basset Hounds. These breeds are more susceptible to the so-called Hansen Type I degeneration, in which the nucleus pulposus escapes quickly and suddenly.

Hansen Type II degeneration is more likely to affect larger dog breeds and is characterized by a slow, chronicChronic refers to a condition or disease that is long-lasting or permanent. Chronic diseases often develop slowly and can lead to persistent or recurring health problems over time. prolapseProlapse refers to the falling out or protrusion of an organ or part of it from its normal position, often through an opening. In animals, this can include, for example, a rectal mucosal prolapse or a vaginal prolapse. in which the annulus fibrosus gradually degenerates and the nucleus pulposus gradually presses on the nerves.

Traumatic events, such as a fall or accident, can also triggerA trigger is a stimulus that elicits a specific reaction or state. In veterinary medicine, this can refer to emotional responses, such as fear or aggression, or medical conditions, such as seizures in dogs and cats. or worsen a herniated disc, especially if a disc is already damaged.

The symptoms of a herniated disc in dogs vary depending on the location and severity of the prolapseProlapse refers to the falling out or protrusion of an organ or part of it from its normal position, often through an opening. In animals, this can include, for example, a rectal mucosal prolapse or a vaginal prolapse.. However, common signs include back pain, stiffness, and unwillingness to move. The dog may have difficulty getting up or lying down and often shows a hunched back.

In more severe cases, neurological symptoms can occur, such as weakness or paralysis of hind legs. The dog may also show incontinenceIncontinence refers to the inability to voluntarily control urine or stool, leading to involuntary loss. There are various forms, including urinary incontinence and fecal incontinence, which can be caused by different factors. or difficulty urinating and defecating if the prolapseProlapse refers to the falling out or protrusion of an organ or part of it from its normal position, often through an opening. In animals, this can include, for example, a rectal mucosal prolapse or a vaginal prolapse. occurs in the lumbar region.

Another possible symptom is the loss of pain sensation in the affected limbs, which indicates serious nerve damage and requires immediate veterinary treatment.

Diagnosis

The diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients. of a herniated disc in dogs begins with a thorough clinical examination in which the veterinarian checks the dog’s neurological function and looks for signs of pain or limited mobility.

Imaging procedures are crucial for an accurate diagnosisA diagnosis is the identification of a disease or condition by its symptoms and/or results from diagnostic tests. It is the first step in the management and treatment of patients.. X-rays can show gross changes in the spine, but advanced techniques such as magnetic resonance imaging (MRI)Magnetic resonance imaging is an imaging technique that uses strong magnetic fields and radio waves to create detailed images of the inside of the body. It is used in veterinary medicine to diagnose diseases of the brain, spine, and other organs. or computed tomography (CT)Computed tomography (CT) is an imaging technique that uses X-rays and computer technology to create cross-sectional images of the body. It enables a detailed view of bones, organs, and other structures and is used for the diagnosis of injuries, diseases, and for planning medical interventions. are required for detailed information. These methods provide detailed images of the soft tissues and can determine the exact location and extent of the disc prolapseProlapse refers to the falling out or protrusion of an organ or part of it from its normal position, often through an opening. In animals, this can include, for example, a rectal mucosal prolapse or a vaginal prolapse..

In some cases, myelographyMyelography is an imaging procedure in which a contrast agent is injected into the space around the spinal cord (the subarachnoid space) to visualize structures in the vertebral canal / spinal canal and the spinal cord., a special X-rayX-ray is an imaging technique that uses X-rays to create images of the inside of the body.

Therapy

The treatment of a herniated disc in dogs depends on the severity of the symptoms and the extent of neurological impairment. In mild cases, conservative treatment may be sufficient, including rest, analgesics, and anti-inflammatory drugsAnti-inflammatory drugs are medications that reduce inflammation. They can be divided into nonsteroidal anti-inflammatory drugs (NSAIDs) and corticosteroids and are used in dogs and cats to reduce Inflammatory conditions and Pain..

PhysiotherapyVeterinary physiotherapy encompasses a range of treatment methods aimed at improving the mobility and well-being of animals through exercise, massage, and other manual techniques. and controlled exercise can also be part of conservative treatment to strengthen the muscles and promote mobility. It is important not to overexert the dog during the recovery phase.

In more severe cases, especially with paralysisParalysis is the complete loss of muscle activity in one or more areas of the body, which can lead to immobility and loss of sensation. Paralysis can be caused by injuries, illnesses, or disorders of the nervous system. or severe pain, surgical intervention may be necessary to relieve the pressure on the spinal cordThe spinal cord is a long, narrow bundle of nerve tissue located in the spinal canal of the vertebral column. It is part of the central nervous system and transmits nerve impulses between the brain and body.. The most common surgery is hemilaminectomy, in which part of the vertebral bone is removed to allow access to the affected disc.

PostoperativePostoperative refers to the time after a surgical operation. This phase includes recovery and the management of possible complications after the procedure. care is crucial for recovery, including strict cage rest and regular follow-up examinations to monitor healing progress and avoid complications.

Prognosis and follow-up care

The prognosis of a herniated disc in dogs depends on several factors, including the severity of the neurological deficits, the duration of symptoms before treatment, and the chosen form of therapyTherapy refers to the treatment of diseases or disorders with the aim of alleviating symptoms, promoting healing, or improving quality of life. Therapies can be medicinal, surgical, or through other medical interventions..

Dogs with mild symptoms and no neurological deficits usually have a good prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop. and often recover completely with conservative treatment. With timely surgical intervention, the prognosis is often favorable even for dogs with more severe symptoms, especially if pain sensation is preserved in the limbs.

Dogs that have lost their pain sensation have a poorer prognosisThe prognosis is the prediction of the likely course and outcome of a disease based on the general state of health, the nature of the disease, and the response to treatment. It can provide information on how a disease is expected to develop., and the success rate of treatment depends heavily on the speed of intervention.

Prevention

The preventionPrevention includes measures taken to prevent diseases or injuries. In veterinary medicine, this includes vaccinations, parasite control, and health monitoring. of herniated discs in dogs requires a combination of genetic selectionSelection refers to the process of natural or artificial selection of specific individuals for reproduction, based on desired genetic traits. In breeding, this is applied to promote specific characteristics in dogs and cats., weight control, and appropriate physical activity. When choosing a puppy, it is advisable to pay attention to the health of the parents, especially in high-risk breeds.

Maintaining a healthy body weight is crucial, as overweight puts additional pressure on the spine and increases the risk of a herniated disc. Regular but not excessive exercise helps to strengthen the muscles and support the spine.

For dogs that have already had back problems, the use of harnesses instead of collars can help minimize pressure on the cervical spine. Also, avoiding jumps or abrupt movements, especially in dogs with long backs, can reduce the risk of a prolapseProlapse refers to the falling out or protrusion of an organ or part of it from its normal position, often through an opening. In animals, this can include, for example, a rectal mucosal prolapse or a vaginal prolapse..
