The best investment that I have made in a long time! I inherited a 4 year old maltese 2 years ago and have felt like a prisoner in the home since. He dictated when he got attention, and we had NO control over him. We had a 3 hour session, and my fiance' and I couldn't belive our eyes! The same dog that wouldn't respond to any of our comments (or give us respect) was now doing exactly as we asked. He has done a complete 180 degree turn of his old self. He was super hyper, had separation anxiety, and had to be the center of attention. Now we have control and he treats us with the respect! Well worth the money!!!!
