Seizure triggers in dogs

As the seasons begin to change (yes begin, we had snow here last week!) triggers for things like allergies, migraines, and even seizures become topics of conversation. What are common seizure triggers? Are they the same for everyone? Are human triggers the same for canines? Let’s look…

Environmental

The environment plays a big role. For humans you often hear about photosensitivity; flashing or bright lights. Dogs are very sensitive creatures, physically and emotionally. They can be triggered by barometric pressure changes, extreme heat or cold, and even the bright or flashing lights. Reggie is very sensitive to heat and low barometric pressure.

Physical

Physical factors are very similar for dogs and humans. Fatigue is a big factor for humans. This generally isn’t an issue for dogs, but research shows that the most common time of day for animals to have seizures is morning or night, as the body is changing from its sleep/wake cycle. Reggie has always had seizures in the afternoon/evening. Missing or skipping meals can cause low blood sugar, which is a trigger.

Diet

Humans can be triggered by alcohol and certain drugs and cheeses. For dogs specifically, eating too salty of a diet (don’t give bacon, hot dog treats, etc.) particularly if your dog takes potassium bromide as an anti-convulsant, can be detrimental as this can lead to salt toxicity and cause seizures and pancreatitis. If your dog already has food allergies (like Reggie) processed, low grade dog foods can cause systemic inflammatory responses that decrease the seizure threshold from the synthetic chemicals, preservatives, and emulsifiers that may be contained in the food. There are also some foods and herbs that have been shown to decrease the seizure threshold such as rosemary, sage, fennel, walnuts, and even turkey.

Emotional

Who wants stress? Stress trumps everything, for everyone, for any ailment. Stress is the number one trigger for humans (followed closely by fatigue), and since we can’t ask our dogs if they are stressed out we have to assess their stress levels in a different way. Prolonged periods of excitement, changes in routine, loud arguments, and separation anxiety are examples of emotional stress. During the holidays, Reggie had a seizure in the car after leaving my mom’s house on Christmas. It was a long day, full of people and presents and dog toys and food and not his house- and it was just too much. He had another seizure after we got home. His body and brain were just “relaxing” after being jacked up all day. When Reggie’s dad and I were divorcing and I moved out, the first few weeks were rough. Reggie’s dad told me he would sit in the kitchen and stare and he had a seizure in that first week. It took about three weeks for me to get settled and the regular rotation to begin but Reggie didn’t understand that, he just knew that I was gone and that stressed him.

Other Factors

Some things that are specific to dogs that can cause seizures are their heartworm medications, flea and tick preventives, even vaccinations. Pine can be toxic to dogs and cause seizures; beware of pine scented or infused cleaners, and don’t let your dog drink the water out of the bottom of the Christmas tree. One last item is rawhides and pig’s ear or feet treats. Many commercially produced chews are bleached first, and flavored chews have chemical additives.

Keeping a seizure diary can help track and diagnose triggers. Establishing predictors can actually help you avoid situations and seizures in the first place. Happy health!
