I was obsessed with W:tA for about ten years, so I'll give it my best go - I don't think she was terribly interested in that aspect of the WoD at all. Actual player-character Garou tended to run in small packs that cooperated and had leaders based on merit simply because making it too much about dominance and who kowtowed to whom would ruin gameplay and nothing would ever have gotten done. There were politics at the local and national level because there were thirteen tribes, all of whom had different charateristics and goals and ideas about how the Garou Nation as a whole should be handled, but it depended a lot on your campaign how much that interfered with what your players were doing. You could just spend all your time taking on the Wyrm and trying not to get noticed by humans and not ever have to worry about whether or not the next pack along was going to be bothered. They were usually too busy fighting for their lives too to care.
You didn't see a lot of civil vamp-were interaction, nor can I imagine a situation where a lot of it might have occurred- vamps always registered as having Wyrm taint and that did not endear them to the Garou. If they tended to help humanity I think they read are more Weaver than Wyrm, but even then it's only Glasswalkers that are going to be totally okay with that. It was pretty much a decided thing that a single Garou could rip a low to medium-level vampire several new ones; they were built for combat and got lots of Soak right off the bat and didn't take any agg damage that wasn't silver. However higher-level vamp characters with a lot of dice in combat disciplines could deal with the damage and inflict their own, especially if you had a player or DM who knew how to use their mind skills properly, so the older and wiser the vamp got the more it equaled out (and eventually tipped in the vamp's favor if it was old and wise enough.) You definitely wouldn't see the Garou (or any other of the shapeshifters) automatically working with vampires or pimping out packmates for favors from the local vamps, or asking for the same in return. Which was still happening in the early AB books; Raina and Jean-Claude traded personnel (and themselves) back and forth like baseball cards to grant favors purely on sexual merit.
I think in the end LKH's estimation of wereanimals begins and ends on the words "flunky" and "sex toy" and that absolutely would not fly in the WoD.
