Not sure if my toy poodle is having seizures, can anyone help clarify?

My toy poodle is 2 and half years old and has been having seizure like episodes every few months, but they don't really fit the "normal" symptoms of a seizure.
I can usually tell she is about to have an episode when she comes to me frantic to be picked up and be in my arms. She then starts trembling and pushes herself into me as much as possible. Sometimes her front legs will spam, however if I hold her nice and firm against me this usually doesn't happen. She will then push her face into any crevice she finds on my lap (usually my armpit area) and I just hold her. My mum is usually there with me when this happens and we one day tried giving her and ice cube because she was panting and we wanted to help her cool down. The ice seemed to help her get back to "normal" a bit quicker. Now when she is about to have an episode, we get a cup of ice ready and periodical throughout the episode we offer her ice. Sometimes she licks the ice straight away and the episode stops almost immediately. Other times she just looks at the ice and pushes her head back into me until she eventually takes the ice. We think the ice gives her something else to focus on when this is happening.
After she has stop trembling and finished her cup of ice, she is very still and quiet. She usually stays on my lap, not moving for a long time. She is not one to sit in one place for very long, especially on my lap as she gets hot fairly quickly, but after an episode, she stays on my lap, dead still for at least an hour if not more sometimes. After her "rest" on my lap, she goes back to normal (within a few hours) and wants to play, eat and cuddle like normal again.
She does not loose consciousness at all and keeps control of her bowls and bladder throughout the whole episode.

If anyone could help shed some light on what is happening to her, I would really appreciate it. The vet wants to put her on anti-seizure meds as soon as possible but I don't want to do that if she doesn't need them.
