My Welsh Corgi had a severe case of reactivity with other dogs and people. I had spent 5+ months of training with another trainer that used positive reinforcement only techniques which could not get the reactivity under control. I decided to reach out to Mango Dogs for help since they used a balanced approach to dog training because positive only was not working. I was hesitant about using ecollars because of the stigma that goes with them and the fear of hurting my dog, but Justin was able to train me to use them correctly. I cannot put into words how night and day he became after training with Justin for only 2 weeks. He is a completely different dog. I can now recall him and keep him calm in front of other dogs and people. I can now take him to public places without him completely losing his mind. He is also happy to put the collar on because he knows he gets to train and have fun. I cannot thank Justin enough. Mango Dogs is 100% worth it. The balanced approach is the way to go. It creates a better relationship with you and your dog.
