When I got McKenzie I thought I was pretty clued up about raising a puppy. I did it before with my dad and that dog turned out perfectly. I still took her McKenzie to puppy class, but basically, I knew what I was doing. When McKenzie was 5 months old I decided that crating was actually a very good idea and now I'd never be without a crate. Now she is 7 months and becoming a bit more challenging I'm thinking a clicker actually sounds like a very good idea! So maybe I didn't know as much about raising a puppy as I thought I did!
