Hello, I keep hearing about high drive pups and couch potatoes, how about a middle of the road pup what are they called? When I hear high drive I get concerned I may do the dog a disservice since I am a first time GSD owner, but a couch potato sounds to low maintenance since I am physically active and have a particular job of protection which I am willing dedicate everyday to train my dog to meet his goals. I definitely want a working line male sable at least I got this far. I never thought choosing a GSD entailed so much research, but now that I'm in it I might as well become as knowledgeable as I can and this forum as been an invaluable source. Thank you to all that have helped me along the way to choosing my life long companion and protector. Any thoughts will be much appreciated. Thank you and have a nice day.
