Nothing less than amazing. My two boxers had been to countless trainings and schools. I saw results after the first week. I'm now able to walk the dogs and use the training aids in a correct manner. After taking my giant boxer, Tyson, to the vet and having the vet shake as she listened to his heart, I spoke to Justin and he accompanied me for the next visit. He has really done above and beyond. I recommend him to anyone that has dogs big or small. He is consistent and honest but I always knew he cared about my Tyson and Layla.
