The official history of the Weimaraner begins on June 22, 1897 when a club for the “pure breeding of the silver-grey Weimaraner pointing dog” was formed in Erfurt, Germany. The breed’s development since that time is relatively well documented. The historical record from before that time is much less clear. And since the further back it goes, the fuzzier it gets, all we have are theories based almost entirely on speculation.
