So to summarize : 120 Chiv PS, and with the remainder points, give the pet at least some stam regen, frankly this pet looks like nicely made on page 1 - awesome. I would just put 5-7 stam regen at least. Hit points and rest are ok.
Oh..and even more important, make sure damage modifier is maxed 24-33 or your effort is wasted. In the last stage of advancements, I would bump damage modifier to max before doing anything else. GL friend. Upgrading is tense for me also, being new to the system. I like the idea of using Test center to check out ideas also, and will start that I think.
