Our youngest GSD is 15 weeks, and completely house broken. From the day we brought her home (at 8 weeks), I've been by her side. I take her out on a schedule, and she has slept with me every night since she's been here. She stays on our bed from about 10:30pm, until 5-6am every morning. At first, during the day, I would take her out about once an hour, then I pushed it to 2 hours, now it's about every 3 hours. She also has 2 very good teachers. A 10 yr old GSD, and a 10 yr old Husky. They're both great dogs, so she's learning a lot from them. We also have a 3 yr old GSD, but he's not home all the time, he travels with my Husband. With all of our dogs we go in and out the same door every time we take them out, so now our 15 week old will go sit by the door, and wait. They're very smart, so take full advantage of that. Routine is the the key. We also have never crated our dogs. Thankfully I'm a stay at home Mom, so I'm able to keep a set routine. I can also leave for a few hours to grocery shop, etc, and come home to no accidents, and nothing chewed up. We've been blessed with some amazing dogs.
