If you are planning to train as a dog trainer or you just want to understand more about your dog, then this is a must-have book. Turid Rugaas explains simply about dog body language and after you have read this book, you will never look at a dog in the same way again. The subtle body language of dogs that you didn't notice will suddenly leap out at you. For me, most of my nervous dog's behaviour started to make sense. Turid is a very well known dog behaviourist in Europe and I know people that have been trained by her who all say it was a fantastic experience. Please also buy the DVD that is available, because it's excellent too.
