This e-book is a life-saver! Figuratively AND literally. It is full of helpful links including many video examples. It’s like having a professional dog trainer at your fingertips coaching you along the way. I recommend this book BEFORE any puppy class. This book goes well beyond a puppy class.
It can be helpful for dogs with fearful or over-reactive behaviours, as well. The process will be slower, but the principles are similar.
It is for sale at Dogwise (click here) and where ever you buy your e-books.
