That is what I know them as. I don't own one but have looked into it. Montana does not allow blood tracking wounded animals with a dog(dumbest thing I ever heard), so I have put off getting one. I have Deutch Drahthaars right now, totally in love with these dogs. My breeder says the jagdterrier is the toughest dog pound for pound in the world. I have never even seen one in person, very rare breed here I guess.
Does your dog get along with other dogs? I have heard they are one dog one owner one family dogs?
