They smell their asses then they know where they’ve been, what they eat, who their family is.
It probably doesn’t smell good but it’s not like they can ask each other questions like “Hey are you a prey animal? Do you eat dogs? Are you one of ours?”
I mean I think they figure those things out off sight and initial body language etc… generally they do the sniffing asses after they’re already pretty confident it’s a dog. I think more of “how’s your mood right now, are you healthy, what are you up to”. I don’t now fully what information they get, but it’s stuff we don’t really think about.

And part of the conversation is how the other dog reacts to the sniffing, takes their own turn, another reaction.
Dogs communicate primarily physically.
