I had a very aggressive dog that did not like people or other dogs. I tried several regular dog trainers that couldn't get near him and couldn't help me at all. Finally I searched for a behaviorist and Michael form Master Dog Training come over for an assessment. He taught us why our dog was behaving in such as way and taught us how to carry out a behavior modification plan. After a few months of us working with our dog following the plan, it's like we have a totally transformed dog now! It took a lot of work on our part, but it was worth it! We only did a few follow up sessions to make sure we were doing things right but for the most part were able to follow the instructions and are happy with the results.
