If that's how she seems to you then you are probably right! The fact that there was such a huge gap between seizures is good, and if need be I bet they can always "tweak" her meds. And there's a lot to be done for arthritis, too - starting with the Cosequin - and continued gentle exercise.
You might also want to stop giving vaccines and just do titers - if you don't know that's a blood test that will tell you if your dog is still immune, and at 9 she undoubtedly is. I think it can be detrimental to a dog's health to give vaccine upon vaccine when the dog is already immune. I found out about titers from my vet when one of my dogs had horrible allergic reactions to his shots. He was also having seizures then. We stopped the vaccines and thank God he hasn't had a seizure in years. I do titers on all my dogs now.
Good luck and God bless!
