Being with the dog multiple hours of the days is not the same as providing the mental and physical stimulation the dog may require. Honestly, it depends on the puppy. The pedigrees indicate a high likely hood of a very driven dog. Active means physical and mental exertion, which only means conditioning the dog to be more physically and mentally capable. You're only building up their threshold to when they will quit. Walk a 4moth old puppy 1 mile to get her to relax, when she is 6 months old you need to walk her 3 miles to get the same result. Its not just walking, there has to be a mental stimulation that is incorporated. We used scent and obedience training. Tracking with food, Hunt the mice in the field, Sit stay heel. You will need to teach the dog new things all the time to keep it from resorting to destructive acts, chewing, digging, marking, and all that. It goes back to purpose IMHO. They will herd until they fall over from exhaustion if you give them the opportunity. Purpose. First time dog owner? I've been around dogs and GSD for about all of my 50 years of life. Its a mixed bag. Its not beyond a reasonable persons capabilities to address any problems they come across. Best of luck with your new addition.Can you define active? I work 8hour shifts 3 times a day. I’m also an independent contractor I work on my own schedule certain days. I think I’m capable of being with the dog most of the time throughout the day.
