Asking for some help tonight. My 12 year old Australian Shepard had a seizure.

He had a seizure this evening and we took him to the vet the examined him and did not find anything major wrong with his vitals. They prescribed him trazadone to rest through the night and then told me if he continues to have seizures to give him phenobarbital which they also prescribed.

Currently he is pacing around the house gently bumping into walls and acting as if he is blind. He also doesn't respond right away when called.

Is there anything I can do to help him at this time? I know he is old and older dogs experience issues. But this is a very hard time for me and I'm just not sure how to handle things. Thankyou all.
