Kennel
Both wars took their toll. Fortunately, by the end of the second world war, the good bloodlines were spread wide across Europe so if losses were suffered, kennels could quite easily get their old bloodlines back.
There are too many kennels to mention but Kurt Ruhnua's 'von Konigshufen' kennel and Swedish breeder, Veroni Sandstrom' 'Sports' kennel were two great kennels that survived WWII and many of today's working dachshunds can be traced back to.
