Zombears/Dogs spawn randomly out in the wilds so they just constantly show up suddenly in the middle of a filed miles away from town(s), nothing you can really do about them except get skilled enough that they minor annoyances at best, Or get a vehicle and run 'em over (Or RSLG* from them).
Moose on the other hand I think only aggro if you get too close to them.

i have been dealing with them, so far almost 60 days and ive killed almost 200 zombie dogs an 80 zombears, an this is with just a single foray into town looking for books, and with that run i killed probably about 200 assorted zombies
