Hello,My name is ***** ***** I am a Vet Tech for over 35 years experience in dogs and other pets.
What you described is a Gran Mal seizure. After the seizure she will be out of it. Not responding is normal that is called the Postictal period meaning after seizure.
At this time there is nothing to do other than getting the dog to a dark quiet room as light and noise can trigger another seizure.
If she starts having anoter seizure Video for the Vet and leave her alone so you do not get bitten. Time the seizure if over three minutes, when it stops get to the ER Vet. If she is quiet just let her sleep.
A seizure is an electrical storm in the brain and can be caused by toxicity,organ issues, Hypoglycemia, a brain tumor, or it can be Idiopathic Epilepsy.
