My advice is don't leave the marital home. That's giving him all the leverage. He can go if he wants to. Also as stated above don't assume you will be left with nothing. I mean, he could burn through all the assets by dragging out the divorce, but that hurts him as much as you. And if they're your dogs they're your dogs.
I am not a lawyer, but a friend got divorced recently and he had to play alimony based on the length of the relationship, not just the marriage, because they comingled finances and insurance for several years before tying the knot, so don't assume if, for example, he was the breadwinner that all the money is his.
Honestly, I'm not sure this guy sounds like someone I'd WANT to be married to, given he seems to present you with a list of demands and your choice is simply to acquiesce. But don't just do whatever he says without standing up for yourself, that's kind of what led you here.
If he's determined to end the relationship over this, there's not much you can do. But at that point you need to think about what's best for YOU, not HIM.
