Here is my 2yr old male DDB George..... He isn't what would be considered a show DDB, however he's a supreme athlete and extremely vigorous.... This dog is an extremely fast runner and seems to have endless energy, even on a hot summer day...He is also extremely powerful, amazingly strong actually . He is very distrustful of strangers and very very protective... He is good when he's out on his leash, but heaven forbid a stranger intrudes on his territory..... He is very dog friendly and plays all the time with smaller dogs, he's very gentle and careful not to hurt other dogs....IMO he may represent what a working DDB should be...
