I have 2 Drahts, two different breeders. First one is an older female (11). She is smaller (55 lbs), slick coated and an excellent hunter.
Was always on the hunt until the last couple of years, she has slowed down. Is in good shape, still hunts effectively and has not one sharp or protective bone in her body. Good swimmer, retrieves well and is great on cripples. Second one is 80 lb male. Class clown, but will bark at strangers.
I refer to him as "a fullback with speed". Goes up the middle all day long, cattails, ravines, draws, cold weather, warm weather he runs effortlessly all day. Points, retrieves, and is not dog aggressive. he will defend himself but would rather be playing. A handful in the house, hoping he slows down a little soon. Agree with earlier poster, they do better with humans than without.
