I have a Drahthaar and a German Wirehaired Dachshund, both come from german hunting lines.
The Drahthaars are amazing as versatile dogs, they are just incredibly smart dogs and a great "do it all" dog for the avid hunter. Very active, will never get tired, and can hunt all day. They also make a great family dog as well, my kids love her.
The GWD comes in a smaller package, easy to travel with on hunts. Stable temperament and just great family dogs. I find that the tracking style (slower and less pull) of this dogs, fits me better as a bowhunter to use as tracking my wounded game in my area.
Both breeds have some great testing programs that encourage you to prepare your dog as they are maturing. It is so important to give them the exposure at the right time, because genetics plays a huge role and is important as a beginning point, but the owner (and the exposure it gives to the pup during the first 6-8 months) plays an equally important role on having a good tracking dog. It takes a lot of time to have a finished dog (if there is such a thing!).
Great post!
