Hi,
Seizures can occur for no apparent reason. Most of the time the onset of seizures in dogs is between one and five years of age and there usually is a fairly long interval between the first seizure and subsequent seizures when they occur.
Seizures can occur as a reaction to medication, allergies, toxins, other diseases, fevers and anything else that disturbs brain function. These seizures are sometimes referred to as reactive seizures or secondary seizures. It is often possible to figure out the cause of this type of seizure based on the history of another illness known to lead to seizure activity, the clinical signs at the time of seizuring or a known history of using a medication that may lead to seizure activity. Allergies are a lot harder to rule out as a cause of seizures, especially food allergies.
I would strongly recommend speaking with your vet and having a full workup done to see if they can determine the cause and begin any needed treatment. There are several different treatment options, but it is first advisable to speak with your vet to try and narrow down what is causing the seizures.
