Hi, Seizures can occur for no apparent reason. Most of the time the onset of seizures in dogs with primary epilepsy 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.Since this is just starting I would assume it may be a reaction to something new or something in the dogs environment. Though there could be other underlying conditions causing the problem. Your vet may want to set up a MRI and do some xrays as well as blood work to make sure there are no other issues at play here. There are medications that can be used to treat seizures so the sooner you get the dog in and get a full examination the sooner your vet can try and get started on a treatment program that will help. They typically get worse over time so treatment is better early on. I would strongly advise you to set up a appointment with your vet today or tomorrow.
