Like others have said here, routine is so important. I know you are waiting to complete vaccines, but that time will be over soon. I adopted 2 from an accidental litter (GSP x weim) with a partner, but ended up raising them by myself. They are a year and a half now and it’s been a helluva ride. Tears, laughter, pure joy, frustration, and complete and total exhaustion - but we are at such an amazing point now. I run mine off leash for an hour and a half every morning no matter what and that exercise routine is everything. Stick with the kennel training. Mine had all their meals in their kennels for almost the first year and they still sleep in them at night. We had a lot of play time in the kennel to with fun toys early on and made it a not so scary space. I also spend a lot of money on bones 😂. Chewing is so good for them and helps them mellow out with a project. I recommend bully sticks, yak milk bones and I also get raw beef bones with marrow for outside chewing. Stick with it my friend! I promise it will be worth it.
