I'm new to formal dog training so I've been reading up about different methods. I think I understand the concept behind the clicker method, but I was wondering if I would really need a clicker. Wouldn't just snapping my fingers work? It's not that clickers are so expensive or hard to find. I'm told you can find them in any pet supply store and that they are super cheap ($2-5). My problem is that I'd probably lose it or misplace it in the other room and be searching for it just at the moment that the puppy is doing the right thing. Which would defeat the whole purpose. What do you think? Could I use the same method but snap my fingers instead?
