We needed help with our 60-lb., 4-month-old German shepherd puppy. He was jumping up on people and chasing our cats. We saw results within the first 5 minutes. He got better and better over the first week. After the first week, we had our family over for Easter. Axel was able to come in with a room full of people and stay under control without bothering anyone. He stopped chasing the cats during the first session. He is so much happier now because he is not always getting himself in trouble and being yelled at. He enjoys car rides now, which was something that terrified him before. Axel's life is getting better every day thanks to Doug!
