That would be wonderful, a seizure alert dog! A while back I saw a video of one in action. His (or her) person was seemingly just fine one minute and then started to seize and the dog was immediately responsive, barking and alerting others to the situation while also guarding the person protectively. I also saw another video where someone with autism was having a "meltdown" due to acute anxiety and again the dog in that situation was wonderful, immediately made sure the person was in a safe environment and then just cuddled right up to her, pouring out consistent love, caring and reassurance as the person struggled through the meltdown. These well-trained dogs are absolutely wonderful and undoubtedly life-saving in some cases. If there is any way that you would be able to get one, you really should! I imagine that there's paperwork and all sorts of documentation and such that needs to be done initially, plus of course a period of time spent in training with the dog as you get to know each other and both prospective owner and dog learn what is expected. Especially since you spend much of each day alone, a trained seizure alert dog would be a very good safety measure in addition to whatever else you and your family have already set in place. Go for it!
