Flipping a coin, no, that would be rather silly. But I understand what you mean by that, and no, I would not automatically save the baby first. As I said, I make no difference. Even though you don't agree with me, I want to explain something that you could keep in mind. You should think of it like this:
I do not think of both to hold the same value as most people give dogs (i.e. rather low compared to humans); instead I value both just as high as most people do a baby. I hope the difference makes sense. Seen it as most people do, one might look at it as if though I have moved the rest of the living creatures to the same "level" as they put humans on, which is very high up. I hope I've explained it somewhat adequately even if you don't think the same way.
