When i was waching this video i thought wow beautiful dogs, realy they are great!!
When i watch the training i got annoyed. A man, who my dog attacks, get the chance to pet him ( but also stab him in the neck or what ever) because the dog is sooo focused on something else.
He should never be the person who gives the dog a reward or stimulation .
But this is my way of thinking.
It is cool you work with your job so at that pint great job and nice dogs.
