She has had a few seizures in the past few weeks but several tonight
Seizures in dogs can indeed be quite alarming, and it's crucial to address this issue promptly. Seizures can stem from various causes, such as epilepsy, toxins, metabolic disorders, or even brain tumors. Given that your dog has experienced several seizures tonight, this is a serious concern that requires immediate attention.
First, it's important to stay calm and ensure your dog is in a safe environment where she cannot hurt herself. Remove any objects around her that she might bump into. Next, try to time the duration of each seizure. If a seizure lasts more than five minutes, it is considered an emergency.
Given the frequency and severity of the seizures tonight, I strongly recommend seeking immediate veterinary attention. Seizures can indicate a serious underlying condition that needs prompt diagnosis and treatment. Your veterinarian can perform the necessary tests to determine the cause and provide appropriate treatment to manage the seizures.
