Yet you feel the weight of being unable to make the right choice about the humans so keenly that you would sacrifice yourself rather than make the choice at all. There's an acknowledgment of moral responsibility to humans there if some fairly backward utilitarian calculus. The life you seem to value the least in this scenario is your own after all, as you said, you're gonna die anyway. Why not sooner than later? Your dogs are gonna die anyway too, so why value them more than yourself. I would posit that at least part of the reason why you value your own life so little is that you are miserable having cut yourself off from the primary source of meaning and pleasure in human life which is connection. It has true intrinsic value to those who experience it, and by virtue of its nature, intrinsic value cannot be justified through instrumentality.
