Murphy responded remarkably well to the training techniques. After the first lesson, he already seemed to respect me as the leader of the pack. These techniques seem to be much more effective than any we've learned at our puppy obedience classes. These techniques are amazing! Murphy did very well for about 3 days after our initial training session. He still responds to the commands/techniques, but it seems to take longer for him to respond. He is very strong willed, but I feel with lots of practice, over time, he will cath on & be more passive & willing to please.
