This great book submit the clickertraining. It has a very big profit for me too, because I learned the clickertrainig from this book. The book submit the six species of clickertraining, and help us to understand the essence of the clickertraining. I suggest this book for everybody who wants to start the clickertraining with her/his dog.
The clicker is one of the best training vehicles. It help the dog to learn faster things, than the traditional way.
The dog whistle is good for so many things, we usually use it for training, but we can use it for else.
There are so many muzzles: small, big, latticed… The selection is huge! We usually use them for dogs who aggressive, biter or mistrustful towards people or other dogs, but we can use them at the veterinary surgeon.
