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.
With can foods, there seems to always be either a lot of fat, sodium or just a tonne of preservatives in the foods. I live quite an active and healthy lifestyle and I generally eat quite healthy, so the reason I bought a dehydrator is so that I can take my own fruits, vegetables and my own cooked meals and dehydrate them for a later date. This works well for me as I find I am being a bit more frugal by taking my own easily made meals and snacks to work, outdoors and even having them when I am too lazy to cook at home. That, and anyone else in the family that enjoys snacks seems to like it as well.
For example, have you considered the need for feminine products?  What about canes, walkers, and manually operated wheelchairs?  Pets need food, crates, and toys to keep them occupied while the rest of family members are recovering from chaos.  It will be impossible to cover every contingency but be aware of what those needs are now then prioritize those that you deem most important.
When somebody speaks of a ‘credit collapse’ , I don’t think anyone can possibly speculate or define what that possibly might be, or how much, or where, or really anything specific enough to be meaningful. The problem with this type of hysteria and hand-waving, is that without specific definitions, or possible implications, it leaves any listener up in the air, grasping at ghosts, and no real solution. So all it does is provoke anxiety, as you can’t possibly prepare for any potential threat or ‘enemy’ that you don’t know anything more about than someone’s vague notion. Further, Its impossible to prepare for every single scenario, that anyone can imagine, let alone even be possible for worst case, as no one has a clue what worst case is, or will be. If any reasonable business leader such as a CEO attempted to prepare for such vague notions as mentioned here, the CEO would be ruled insane, and the board would summarily fire him. Instead of doing this scene here, listening to what will almost assuredly turn out to be in hindsight, false prophets, and making your day a nightmare, why not live each day as if its your last, live in the moment, enjoy it and your time with your family, or work colleagues, and make the best of THAT MOMENT ? I’d be shocked if at least 75% of the listeners here, weren’t either seeing a shrink or taking anti-depressants or anti-anxiety medications of some sort. Its not a knock, but seriously people, try taking a ‘chill pill’ (placebo and call it that) like a Vitamin C, or have yourself a glass of wine, at the end of the day.

Potassium iodide. This was actually not my idea, and on the paranoia scale I think this one’s pretty high up. During the George W. Bush administration, my former boyfriend’s mother, a M.D. who had trained to care for people who’d survived war and other traumas, insisted we keep a packet of potassium iodide, which provides some protection to the thyroid in the event of a dirty bomb. After the breakup, I kept the Le Creuset, and he kept the KI. So it’s paranoid, whatever, potassium iodide is cheaper than Le Creuset.
For my stockpile, I use several Aqua-Tainers with categorical labels marked on them for drinking water, hygiene water (dishes and showering), toilet water and garden water. My priority is obviously drinking water, but any dishwater I have I reuse as toilet water. While it might seem overkill, keeping an eye on your stockpiles is good practice to get an idea of how much your daily consumption rate is, and where you can find ways to re-use or use less water.
Lokey teaches students agricultural skills and says she came to Wild Abundance because she wants to show her students how to build a basic cold frame: a wooden enclosure with a transparent roof that can be used to keep seedlings warm in winter. That way, no matter what happens, they’ll have the tools they need to grow fresh fruits and vegetables all year round.

If the day of reckoning stretches on beyond a few months, however, the ability to grow one's own food will become paramount. Seeds and gardening tools, therefore, should be on everyone's doomsday supply list. Opt for so-called heirloom seeds. These seeds yield disease-resistant crops that produce yet more seeds season after season, unlike hybrid seeds used for mass-cultivated, commercial crops, which can develop into sterile plants.
