I just bought a clicker and scared myself by the first click! It's TOO LOUD! I wanted to use the clicker with my pup (coming in 11 days), but now I'm afraid that it will be too loud for him. I bought the cheapest and simpliest clicker. I know that there are some more expensive electronic ones with volume control. Do you have any experience with this loud clicker and your pup? Do I have to go and buy the expensive one? I don't want to scare my dog!
