Seizures happen when normal brain functions are disrupted. We often don’t know what causes a dog to have abnormal activity, but sometimes there may be links between seizures and diet.
- A 2012 case study describes a Saint Bernard puppy who developed seizures due to nutrient deficiencies while he was fed a homemade diet.
- Hypocalcemia and hypomagnesemia are known triggers for seizures in pregnant and lactating females.
- A common amino acid in commercial dog foods, glutamate, may trigger seizures.
Recent studies also demonstrate that diet and nutritional supplements may help to prevent seizures in dogs. Feeding a ketogenic diet appears to improve cognitive function and may reduce seizure activity in some dogs. Other research suggests that supplementation with medium chain triglycerides may reduce seizure frequency and severity.
