If you have a friend, (in our case a family) and one of them is Bi Polar, consider NOT partnering up with them,. Even if one of the adults is very well versed in many survival skills.and the adult who is Bi Polar is good at thinking on the fly. No matter how well balanced and in hand the one seems, at some point their condition will manifest and it could well spell out major problems over all. If they are addicted to CHAOS (and many of them are), they will go out of their way to CREATE issues of some type within the group that will do NOTHING of value to insure survival
Hate to break it to you, but your dog probably has a better chance of making it through a total societal collapse than you do. A quick Internet search of "dog survives" lists everything from drowning to being shot, from bear attacks to war -- whereas the closest you've ever come to "surviving disaster" is getting your wisdom teeth pulled, and even then it was only with the help of a cadre of trained medical professionals and a carton of the strongest painkillers on Earth.
To me, the best option is to store emergency food. How much? If you have none, store enough for a few days. If you have enough for a few days, get enough for a week. How much you store depends on what time frame you think you're at risk for having to be completely independent. The early settlers of the southwest liked to store enough food for a whole year and still do to this day!
