I definitely think we all understand.. or else we wouldn't be here, trying to help you. We'll do everything we can to help you get your baby back

But yeah, I would try to get the cops involved. If your bf is a police officer wouldn't he know what action you could take? Just wait for now and see what he has to say, maybe you can somehow hold that against him..? It sounds like he's going to lie the way he keeps building up how much you "need to know".. there shouldn't be that much to say. He STOLE your dog, period.

Other than that, I agree with everybody else, try not to get too worked up when you're talking to him or he might freak out and give the dog away or something. I don't know him or anything, but I'd just be careful around him.
