So we just brought home a 10 week old GSD pup about a week ago. We had been going to see him since he was 3 weeks old. Over the last couple days he has been getting more mischievous which I expected. I suppose he his comfortable now and really getting into stuff. It hasnt become a problem because we stay on it. Any tips for him at 11 weeks? This is my first GSD and i want to bring him up right.
