Thank you again!
It looks like I might have to start crate training him. Do you guys have any resources you'd recommend I start looking into? We used to live in a small apartment and I felt horribly guilty leaving him in a tiny balcony with toys and food and water. He looked so sad every time I drove by the balcony and looked up to check on him. Now that we're in a house with a backyard, I let him run around so he doesn't get depressed. Even so, I felt so ad leaving him at home by himself (but mama has to work to buy you food and toys and take you to places). Maybe I'm overthinking this. But I don't know how to keep him entertained for 9 hours in a small space, not to mention bathroom breaks, hence I've been so hesitant about crate training. Maybe I'll look for some indoor fence to keep him in a certain area. (Currently, all bedroom doors are closed, so he only has the dining area, kitchen, and empty living room to roam around.)
Trust me, I did not just pick him out of all the breeds and just now started complaining because he's too much work. My husband has grown up with many dogs, and he was working part-time and going to school part-time, so we decided that we could get a German Shepherd. I did hear from an experienced GSD owner that they go through their "teenage" phase around 8 to 18 months, when they get extremely stubborn and do things that drive you crazy. Unfortunately, that's also the time frame that my husband has to leave, which we did not know about until a month after we brought our puppy home. I'm really trying to hang on and train him a little each day and wait until his human papa comes home.
Thank you again for your help!
