It is effective for the dog trainers at Petsmart, but I tried it when I had a 2 month old German Shepherd, and it didn't work for me. What I found worked was using hand signals (like I'd snap my finger and point down when I wanted him to sit) and when he'd respond how I wanted him to, I'd give him a treat. Once he caught on to that, I started incorporating words with the hand signals and he got it. Like kids, every dog learns differently. Congrats on your new puppy and best of luck!
