If you aren't comfortable with the trainer, go somewhere else. I would suggest next time that you attend some training sessions before taking your dog so you can see how the trainer works before letting them handle your dog.
What are your training goals? Pet OB, sport, bitework?
When a dog saves the life of a man, it becomes clear that partnership knows no bounds.
