This is prepper 101 but also make sure your vaccinations are up to date. Rabies is a real threat and people (even tourists) to Thailand for example get bitten all the time. Yes there is something you can do right after you got bitten to prevent rabies but these treatments won’t be available in an all out disaster or collapse.
I often go running in rural areas with rather vicious dogs. I have a small pepper spray with me because of that.
