Personally I am not a fan of electronic collars....however, the dog is clearly happy to be following his handler's commands. I don't have experience with the breed, but as far as I know German Shorthaired Pointers can be difficult to train(correct me if I'm wrong)... So the fact that his dog is enthusiastic and happy to follow out his commands is a good sign. If this is not a bark collar, this may be used for a variety of reasons....for instance, he may use it simply as a precaution if the dog strays. Let's say a strange dog struts towards you showing aggression and your dog loses focus on you. Maybe he's using it as a means of keeping the dog at a close distance, and focused? Not that this makes it okay.....just a possible reason for the collar. Not sure...but very nice video otherwise. =)
