Our German shepherd OB was only 7 months old and already a menace! He would pull hard on the leash, didn't bother to listen and would play very rough with other dogs that made people feel uncomfortable. We even had him train with two other dog trainers with no success at all and then feeling abandoned by these so-called trainers because they felt he was too aggressive. This is where Bob had save my sanity! After our first meeting, I knew he was going to do a great job and was very accommodating with our schedule. We opted for the 2 week boot camp while we were out of town. When we got back, our OB has been great on the leash! Complete turn around! We still need to correct him occasionally as he is still a pup and learning but it has been a blessing. Thank you very much Bob!
