Before they were pets, dogs were workers. They can carry their own supplies without complaint (already making them superior to most humans right now), sniff out food and water, and search for and bring down prey. Some breeds, such as huskies, have been specifically tailored to bust their butts on the barest of rations. Dogs also have a long and storied history of offensive and defensive combat use, making them perfectly suited to attack anyone who thinks they have more of a right to that sweet, sweet snack cake stockpile than you do. Which is to say, your four-legged pal is just a few training sessions and a kickass set of armor away from leading you to your rightful place as God Of The Ragged Desert/Water People.
Pepper spray. An excellent, temporarily incapacitating weapon - very difficult to resist and capable of buying you just enough time to escape. Works quickly and reliably at distances up to perhaps 10 feet; can also stop some animal attacks. Usually not heavily regulated, making it easy to obtain and carry even in places that frown upon other forms of armed self-defense (but check the laws). Pepper spray becomes less effective in strong wind; there is also some risk of blowback, but this is mitigated in narrow-stream products, such as Sabre Pepper Gel ($18).
