Could Your Dog's Thyroid Be Contributing to Seizures?

Many pet owners are surprised to learn that thyroid disorders and seizures often occur together. During more than 40 years as a holistic pet nutritionist, I have found that a large percentage of dogs with recurring seizures also have low thyroid function. While not every dog with seizures has a thyroid problem, it is important to investigate because it is frequently overlooked.

Why the Thyroid Matters

The thyroid gland regulates many functions throughout the body, including metabolism, energy production, body temperature, and the way cells use glucose. When thyroid hormone levels are too low, the body's systems slow down. In some dogs, these changes may contribute to conditions that make seizures more likely.

Hypothyroidism and Seizures

Hypothyroidism is the most common thyroid disorder seen in dogs. Dogs with low thyroid function may experience weight gain, lethargy, skin and coat problems, chronic ear infections, cold intolerance, behavioral changes, and in some cases, seizures. Although seizures usually have more than one contributing factor, thyroid health should always be considered as part of the overall picture.

Testing Is Important

If your dog develops seizures, I recommend a complete thyroid evaluation. A routine screening test may not always provide the full picture, so ask your veterinarian which thyroid tests are most appropriate for your dog's situation.

A Holistic Approach

If your dog has both seizures and hypothyroidism, addressing thyroid health is only one part of the recovery process. Nutrition also plays an important role. Feeding a fresh, balanced diet made with high quality ingredients, reducing unnecessary chemicals, and providing appropriate nutritional supplements may help support overall health and quality of life.

Need Individualized Guidance?

Too often, the focus is placed entirely on controlling seizures while an underlying thyroid disorder goes untreated. If your dog has recurring seizures, make sure thyroid function is part of the conversation with your veterinarian. Looking at the whole dog rather than just the seizures often provides valuable information that can help create a more complete treatment plan.

Every dog is different. If your dog has seizures, hypothyroidism, or both, I can help develop an individualized nutritional program designed to support your veterinarian's treatment plan and your dog's long-term health.
