The mobs once spawned in again, as far as i'm aware, do not despawn until they have been killed. I've come across deer, pigs, necks and other things that i'd hit like once and they were still around that area hours later.

It might be a case of if you don't find a 1/2 star wolf in a pack, wiping them out and leaving the area to let them respawn is a good idea? it worked for me and the pigs.

Ah yeah I've done that too, was the origional method I used to get the 1 star wolves I have now, and now I have heaps of them, the taming process is a good pay off long term I think. Sucks they only usually spawn at night & what not.
