AMAZING !! We have a minnie australian mix. Within 10 minutes of Michael meeting him, he was no longer jumping, scratching, or biting! I have a 6 year old special needs granddaughter who we had to keep by our side constantly for fear Max would bite her. Michael not only helped him to stop but provided a way for my granddaughter to be able to communicate with Max and stop his behavior if she had to do so on her own. Michael was with us for 2 hours but only about 45 minutes of that was spent actually training Max. By the time Michael left our home, my granddaughter was laying on the floor with Max. She was tapping his face and he wouldn't even open his mouth, where before he would have bitten her. I have to admit that bringing Michael into our home was one of the best decisions we ever made.
