More: My wife and I are raising a child with special needs. Motor coordination is one area that he struggles with. As a result, having a full sized hunting dog in our home was just not a possibility. After a lot of research, I found the Jagdterrier breed. I chose to purchase a dog of this breed because they have a big motor and a huge prey drive. He has an excellent nose and is really taking to the idea of flushing upland birds.
