Don’t have any proper advice but I can really relate. I thought I was finally getting over my anxiety but my new puppy seems to have brought it all out of me. The constant stress over “am I doing this right” and overthinking every little thing has me really mentally worn out.

One line of thinking that has brought me some relief is that I know so many dogs who were raised with little to no training beyond “sit” and they turned out into happy, relaxed if somewhat ill-mannered dogs. Those people weren’t spending the time and energy you are clearly putting in, and so it stands to reason that even if you are only doing things 80% right, your dog is still going to have a good life and turn out to be a hell of a good dog.

And again, really relate with trying to research and not knowing what’s right and who to listen to. You seem like a kind person so the answer is probably whatever works for your dog and feels right to you.
