Have you ever clicker trained? If not, I'd keep the clicker on the shelf for now. That's what I did for Peggy's first 6 months or so. I wasn't confident I was mentally or physically coordinated enough to use that particular tool effectively while trying to wrangle a puppy.My girl is super old. She is 14 and has no teeth. She is a rescue that I have had for a couple years now. I did buy a clicker but have been too stressed to even try it. I feel like he has no desire to listen to me at all. I know I need to start just doing it.
You start puppy class soon, right? I'd focus on having fun with your puppy between now and then. Learn each other.
