how often does a gsd come in season

Like (almost) all other breeds, on average every 6 months.

Unless, like my gsd, the little dear comes in every 4 months :o

ps, think I got that emoticon wrong!!

One of my old GSD's used to come in once a year :rolleyes:  not only resembled a wolf, but thought she was one :P

But as JG says, generally for most bitches, once every six months or thereabouts :)
