Can Vitamin B12 Deficiency cause Epilepsy in Dogs?

Updated: Jun 14

Can Vitamin B12 Deficiency cause Epilepsy in Dogs?

While still in its early stages, recent research has shed light on a potential connection between vitamin B12 deficiency and epilepsy in dogs. Particularly in breeds who are susceptible to malabsorption of B12 like Border Collies and Beagles. Let's delve into this intriguing link and understand its implications for the future of managing canine epilepsy.

Understanding Vitamin B12 and Its Crucial Role in Dogs

Vitamin B12, also known as cobalamin, is indispensable for various aspects of a dog's health. It plays a vital role in maintaining a healthy nervous system and brain function, facilitates the formation and growth of blood cells, and supports intestinal health crucial for digestion. While most dogs obtain sufficient B12 from their diet, certain factors such as eating a poor diet, illness or genetic predisposition can disrupt its absorption and lead to deficiency.

Symptoms of B12 Deficiency in Dogs

Insufficient levels of vitamin B12 can result in anaemia, affecting the body's ability to absorb iron. Dogs with B12 deficiency and/or anaemia may exhibit symptoms such as lack of energy, weakness, reduced interest in play, loss of appetite, diarrhoea, weight loss, lack of muscle mass, confusion, and in severe cases, seizures. Recognising these signs early is essential for prompt intervention and treatment.

Causes of B12 Deficiency in Dogs

The primary cause of B12 deficiency in dogs is often related to absorption issues. Certain breeds, including Australian Shepherds, Border Collies, Beagles, Giant Schnauzers, and Chinese Shar-Peis, are genetically predisposed to difficulties in B12 absorption. Diseases affecting the pancreas, such as exocrine pancreatic insufficiency (EPI) and pancreatic cancer, can also impair B12 absorption, leading to deficiency.

In addition, disorders of the small or large intestine, such as inflammatory bowel disease (IBD), can interfere with B12 absorption and contribute to deficiency. The balance of bacteria in the gut microbiome also plays a crucial role in B12 absorption. An imbalance in gut bacteria can disrupt the absorption process, further exacerbating the deficiency.

Vitamin B12 and Epilepsy in Humans

In humans, research has confirmed links between vitamin B12 deficiency and seizures. Additionally, it has shown that the use of anti-epileptic medication can further reduce vitamin B12 levels, exacerbating epilepsy symptoms. These findings underscore the importance of maintaining adequate B12 levels for neurological health and seizure management in both humans and dogs.

New Research is Underway: The Border Collie Study

There is a strong enough correlation between low B12 and epilepsy that a study is currently ongoing by Bristol Veterinary Specialists investigating the potential link between vitamin B12 deficiency and epilepsy in Border Collies. Border Collies can suffer from a genetic condition called Imerslund-Gräsbeck syndrome, which reduces blood and cellular levels of vitamin B12. Due to these findings, the team will specifically be investigating the role of vitamin B12 in epilepsy. This study aims to shed light on the underlying mechanisms and potential treatment approaches.

How Can Owners Help?

Dog owners play a crucial role in supporting their pet's health and well-being. Regular veterinary check-ups, especially for breeds prone to B12 deficiency, can aid in early detection and intervention. Additionally, participating in research studies, like the one conducted by Bristol Veterinary Specialists, allows owners to contribute to advancements in understanding and treating epilepsy in dogs.

How can I test my dog for Vitamin B12 Deficiency?

Testing for low vitamin B12 levels in dogs typically involves a simple blood test, specifically measuring the concentration of vitamin B12 in the bloodstream. This test, known as a serum cobalamin assay, helps veterinarians assess whether a dog has sufficient levels of vitamin B12 for optimal health. Additionally, other blood tests, such as a complete blood count (CBC) and serum chemistry panel, may be performed to evaluate overall health and identify any underlying conditions contributing to B12 deficiency. By accurately diagnosing and monitoring vitamin B12 levels, veterinarians can tailor treatment plans to address deficiencies and improve the health and wellbeing of dogs.

Conclusion: Can Vitamin B12 Deficiency Cause Epilepsy in Dogs?

While the research is still in its infancy we are beginning to understand the role of vitamin deficiencies can play in causing or exacerbating epilepsy symptoms. By being informed of the symptoms and recognising them early dog owners can help ensure their dog's lead healthy, fulfilling lives.
