There are things that you teach your dog as a puppy, much that is learned via puppy kindergarten, or youtube videos. All the basics are covered everywhere, how to sit, drop and fetch a ball. But there is something more important in a puppies life that needs to be taken care of as a priority; its early socialisation period. The period in its life that lasts until it is 16 weeks old that will determine how the dog sees the world for the rest of its life. This is a missing piece of the puzzle that results in most behavioural problems that many dog owners end up seeking behaviour training or pharmacological intervention. Presented here is, I hope, an easy readable and understandable pack of information that the scientists and ethologists know, that you, the new puppy owner really really need to know and understand and put into practice so you can have a better life with your new dog. This is a book about socialisation. Not about going out to dog parties, but about teaching and showing your dog that it can be calm and confident in the big world it has come into. Additionally, the information and techniques in the book can be used to assist with adopted dogs from shelters, fosters and if you are like me, the continual strays you try to help. The information is tried and tested, scientifically sourced and used by professional trainers, Military, Police, SAR and competitive dog handlers the world over. 80% of the dogs brain develops in the first 16 weeks. Make the most of it!
