My first dog was a standard black and tan Daschie. His AKC name was Von Brock Von Huesenheiser. We didn't want to do that to him, so being as Dad brought him home Christmas eve, we called him Nick for St Nick. We had him for 18 years before he got so it was obvious he wasn't having a good time anymore, so we put him down, with the family standing around him. He was a great dog. Fearless even though he would have gotten eaten by most of the dogs he backed down. Only time he did get his butt whipped was by the neighbors 2 pound kitten. He was out of sorts for a week after that. 

Anyhow to me it was obvious this was a Daschie, so good job there. So happy you are back in the shop. I am trying with great success one day, and almost total failure the next, no stamina still. Keep pushing it till you loose the walker, probably won't be long.
