My dog had Epilepsy and it was so sad for me to watch him and to hold him... After a seizure he wasn't himself anymore. He didn't where or what he was or who I was. It broke my heart but we decided it is best for him to pt him to sleep and keep all the happy memories of a very proud dog! He was 9. On the other hand - our family cat turned 23 and she had Epilepsy as well... I think the most important thing is that, if you decide to give tablets, to never be late or even forget one!!!!!!!! That will make things much worse for your doggie...
