Not too sure about the specific details of Brun Cragback & Lug, as I haven't had a chance to look into what they are all about, but that looks like a pretty good Kaya list, all dogs and all.
If you wanted to do a pure dogs list, you could always throw in another war wolf and 5 Warpborn Skinwalkers for those 9 points!
Totally up to you, though I would get a couple of games in with the Brun and Lug before you actually buy the models, as I don't know if they would fit the style of your list or not.
A tiny portion of humanity turned its back on mankind in the waning days of the last Golden Age. Over one and a half centuries later, the PHR has emerged from the shadows as an unrecognisable civilisation, its people irrevocably changed. They are no longer simple human beings, they are post-humans - cyborgs.
