extremely aggressive dog bites trainer over and over! HELP ME Miami Dog Whisperer!

This dog was brought to The Miami Dog Whisperer by his owner because they have been bitten by him too many times and are now terrified of him. This dog truly is what we consider a dominant bully that enjoys intimidating people. In the video you will see The Miami Dog Whisperer and one of his trainers just trying to do a sit command with him and how aggressive he gets fighting them over it. And no, he will not accept food during training which of course made this exercise extremely difficult.
