It is definitely much more complex when the Summoned is a living being, and especially a relatively intelligent being like a wolf (as opposed to a worm or something). 

In my opinion, all of those things you mentioned amount to a metaphysical bond between Val'kur and the wolf, and would indeed make summonings easier to pull off. Again, the main limiting factor I see is that the wolf will be just a wolf. No Bonded super-wolves for novices.
