Understanding Spina Bifida in Dogs
Spina bifida is a rare congenital abnormality that affects the vertebrae of the spinal column in dogs. The condition occurs when there is incomplete growth of the vertebrae around the spinal cord during fetal development. This incomplete growth can lead to a defect in the spinal column, varying in severity depending on the number of vertebrae impacted. While spina bifida can occur anywhere along a dog’s spinal column, it is most commonly observed in English Bulldogs (Wagwalking).
Definition and Classification
Spina bifida in dogs can be classified into three subtypes: spina bifida manifesta, cystica, and aperta. These classifications are based on the type of protrusions related to the spinal cord and its membranes (Wagwalking). The severity and clinical presentation of spina bifida can vary depending on the specific subtype.
-
Spina bifida manifesta: In this subtype, there is a visible defect in the vertebrae, which can range from a small opening to a larger opening along the spine. The spinal cord and its membranes may or may not protrude through the defect.
-
Spina bifida cystica: This subtype is characterized by the presence of a fluid-filled sac or cyst that protrudes through the defect in the vertebrae. The cyst may contain cerebrospinal fluid, spinal cord tissue, or both.
-
Spina bifida aperta: In this subtype, the spinal cord and its membranes are exposed directly through the defect in the vertebrae. The exposed tissue can be vulnerable to injury and infection.
Causes and Risk Factors
Spina bifida in dogs is primarily caused by incomplete growth of the vertebrae around the spinal cord during fetal development. However, other factors can contribute to the occurrence of spina bifida in dogs. Inheritance plays a role, as certain breeds, such as English Bulldogs, are more commonly affected. Environmental factors, including nutritional deficiencies, maternal stress, and exposure to toxins, can also increase the risk of spina bifida.
While the exact genetic mechanisms behind spina bifida in dogs are not fully understood, research in mice has identified several cellular processes that may be involved, such as planar cell polarity (PCP) pathway, cell apoptosis, DNA transcription, and the canonical Wnt/beta-catenin pathway (NCBI). Additionally, maternal diabetes, obesity, inadequate nutritional status, alcohol and caffeine use, and maternal hyperthermia have been associated with an increased risk of spina bifida in dogs.
Understanding the definition and classification of spina bifida, as well as the causes and risk factors, can help dog owners recognize the condition and take appropriate measures to prevent and manage it.

Research and Advancements in Spina Bifida
As research in veterinary medicine continues to progress, there are emerging treatments and ongoing clinical trials and studies focused on spina bifida in dogs. These advancements aim to improve the understanding, prevention, and treatment of this condition.
Emerging Treatments
One significant development in the field of spina bifida treatment for dogs is the exploration of prenatal repair of myelomeningocele. Myelomeningocele is a severe form of spina bifida where the spinal cord and its protective coverings protrude through the opening in the spine. Prenatal repair is performed during gestation and aims to prevent further damage to the spinal cord, as spinal cord damage is progressive during this period. The Management of Myelomeningocele Study (MOMS) demonstrated that prenatal repair can offer significantly better results than traditional postnatal repair (Children’s Hospital of Philadelphia).
Another promising advancement is the use of cellular therapy for the in utero repair of myelomeningocele. The Cellular Therapy for In Utero Repair of Myelomeningocele (CuRe) Trial is an FDA-approved Phase 1/2a clinical trial that utilizes stem cells for the fetal repair of myelomeningocele. This trial shows promise for improved outcomes in children with spina bifida (NCBI).
Clinical Trials and Studies
Ongoing clinical trials and studies are essential in expanding our knowledge of spina bifida in dogs and developing effective treatment strategies. These endeavors aim to identify genetic factors, understand underlying cellular processes, and explore preventive measures.
Research has shown that genetic factors contribute to a significant portion of the risk of neural tube defects (NTDs) like spina bifida. Over 240 mutants and strains have been identified in mice, providing valuable insights into cellular processes involved in NTDs, such as the planer cell polarity (PCP) pathway, cell apoptosis, DNA transcription, and the canonical Wnt/beta-catenin pathway (NCBI).
Additionally, studies have highlighted the importance of folate supplementation in the prevention of NTDs, including spina bifida. Folate supplementation has been shown to prevent up to 70% of NTDs in humans. Mutations in genes involved in homocysteine-folate metabolism have been associated with an increased risk of spina bifida.
By actively participating in clinical trials and supporting ongoing research efforts, veterinarians and dog owners can contribute to advancements in the understanding and management of spina bifida in dogs. These endeavors offer hope for improved outcomes and a better quality of life for dogs affected by this condition.
It’s important to note that the treatment of spina bifida in dogs can be costly. The average cost of treating spina bifida ranges from $1,500 to $8,500, with an average cost of $4,500 (Wagwalking). However, the potential benefits of participating in emerging treatments and clinical trials may outweigh the financial considerations for some dog owners.
As research progresses, it is crucial to stay informed about the latest developments and consult with a veterinarian specializing in spina bifida to explore the most appropriate treatment options for your canine companion.
