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.
Regardless of whether everything is going swimmingly or you’re lost in a whiteout above tree line your boots are one of the most important pieces of survival gear you have. You need them to stand up to the elements and keep your feet dry and comfortable. Irish Setter Men’s Waterproof Hunting Boot is a fine example of the state of the bootmaker’s art.
If you’re ordeal is an extended one you can lash the Ultimate Pro Knife to a small branch to create a spear for catching fish or small mammals. The pommel at the butt end can be used to hammer tent stakes and that little thing hanging from the lanyard cord is a powerful emergency whistle that can take over emergency signaling duties from the tactical flashlight or your long range walkie talkies when the sun comes up. A top-notch knife like this is essential survival gear.
It turns out that when you're down to your last moldy hunk of bread and giardia-laced mud puddle, letting it all melt away in a cloud of smoke for a few precious moments can mean the difference between giving up and giving the rat (eating) race another go. If history has anything to say, it's more common than you think for people to happily give up MREs and gunlord harems in return for hastening their ends with carcinogens wrapped up in tidy paper packages. In traumatic situations like war, cancer sticks are often valued more highly than food. Even in the current (more or less) pre-apocalyptic global economy, cigarettes are one of the stable forms of currency.
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!
