Hi Spartak,
About the dogs, you could find a safe dog deterrent, there are some based on sounds or ultrasounds, and others in spray, similar to pepper sprays, and are safe for yourself, and for the dog. Just carrying it may help you feel safe, and you may not even have to use it.
About jobs, it's not easy if you have not found yet any way to at least lower your symptoms. If you are able to abstain for long periods, and do not have NE very often, than you could be able to manage. If you look sick like once every 4 to 8 weeks, that may be accepted, but once a week or twice a month, and you will be rapidly noticed and tagged.
Other than that, you would have to find a job where you are mainly on your own, like janitor in a store or a building, during afterhours ( they are often left alone, but those jobs are often late in evenings or during the night). These are not dream jobs, but one thing leads to another.
Another possibility is to be a sale representative, or something similar, or a web worker, working at home, thorugh the internet. Than, you can organize your own schedule, so that you do not contact clients and meet them, or do your web work, on the days you are in POIS. You would not become a "5 star seller" or the best web worker in the world, because you will have more days off than normally should, but again, you have to start somewhere.
I hope my suggestions will help you in your reflections.
