Some people seem to think other people and trainers know more about their dogs. Seems odd because you live with your dog you learn from each other. Not like the trainer is physic and knows everything even trainers can be wrong. They may know more what works best but not know as much as the owner. I know that my dog is a fanatic at swimming can go for hours. At times loves to bark when it is a fun happy time. Don't let him bark when frustrated anxious scared or nervous. He has his own indivdual that a stranger doesn't know about that.
