My Sting is from showlines and moderate to low energy depending on how hot or cold it is outside . He is a pet. His daily routine is 1 1/2 miles brisk morning walk, afternoon short obedience session including heeling walk around neighborhood - then his reward, a 10 - 15 minutes of fetch/tug which he loves. Evening before supper, 1/2 hour free time in the fenced in back yard. In answer to your question, though, Sting suits my lifestyle fine, I work from home, and he naps while I work. But if I had wanted to compete, do Schutzhund, tracking, and so on with my dog, I would have looked for a GSD from working lines.
