How to keep my dog alive

So I’m homeless in flordia with my dog Princess, usually before the hurricane and the winter storms we would easily be able to go to a food bank to get food however most became damaged during the storms so now it’s hard to get food anywhere for her I could usually care less about my health I dig through dumpsters and such for food but I don’t need her getting sick off of that mess an I ran out of dog food with the rest of my money I spent for her that was given to me by a good person . Now I’m terrified because it’s been two days an I dont know how long they can go without food..does anyone know places that give away dog food? I tried all the churches and the one food bank opened but nothing.
