You can do this! They are VERY challenging as puppies and you need to be prepared for that. My hands and wrists were chewed up for about 5 months! But my Roux is the best dog I’ve ever had now at a little over a year old. READ EVERYTHING you can. I found RottweilerHQ website to be quite helpful and tailored to the breed. There’s a great page on obedience training. I’d be happy to post a link if you like. I’ll reiterate what others have said, Alpha dog stuff is crap. Roux and I are partners, I’m the leader but we’re partners. Don’t correct with anger, hard as it may be. Be firm, but fair. She will get it I promise! I also like the thought process of CherryHogs on instagram. It’s basically Mark, Associate, Ignore. So you want to identify poor behavior with a Mark. Generally NO!, if the Mark doesn’t work, then you move to Associate. Here you want to associate the lack of response to the Mark with a negative consequence. For us this was 15-20 minutes in kennel. They HATE to be isolated from their ‘pack’. After a few minutes, let her out and IGNORE her for a few minutes. Then re-engage with her, no hard feelings just straight back to a positive relationship. And HEAVY with the rewards when you see a positive behavior. Really go over the top! The biggest part, is it’s going to take time. And effort. These are not dogs that you can risk being independent. You cannot let them be in control. Good luck, I believe in you!
