So, I've had my German Shepherd for nearly 3 years now, and got him at 9 months old. He was a very dominant dog at first, but i got him right out of that. I've done plenty of obedience training with him, and will listen well to all commands he's learned from basic to advanced even still. Ever since i got him he's had boundaries that i have made very clear, clearly set rules, and he never had a problem following them.
Well, until recently. Within the last little while he has actually been breaking rules that were rock solid before. There was never any lax given on ANY of the rules, no leeway for any paws over boundaries. Basically, he is allowed anywhere up until he hits the livingroom, which is a clear line where the carpet begins. A line you can visibly see. The boundary line. Any single paw over that line was always corrected. However, very recently, he has actually begun going juuust into the livingroom when no one is looking. Not right into the middle of it or anything, but to where his whole body is a couple inches over the line to lay down despite the fact he has a dog bed he shares with my other dog and another carpeted mat (far from the line) in the permissible area. We often catch him and reprimand him for it, and all will be fine for a couple of days, then it will happen again.
Also, a few days ago, he actually emptied half the garbage pale. Yesterday, after i gave him a bath, he actually pulled something out of it when my back was turned. Caught him and everything,but he has NEVER been a garbage picker. Ever. In all the time I've had him he has never taken anything out. He may have at most sniffed the lid out of curiosity, but that's it.
Does anyone have any ideas on what's going on here? I'm honestly at a loss. I'm glad to answer any questions if it helps.
