About the pigs. I edited them out not because I think they are non-historical, but because they might get "abused" by the AI's build routine, like wardogs, screeching women and the like.

With dogs I was ok with a unit of dogs every once in awhile in 1.1, but they got old really fast in 1.2 where they were 10 to 25% of quite a few armies I faced.
