An aggressive dog, whether large of small, baring its teeth and growling can be a terrifying sight. Dogs, like children, require boundaries and training in order for them to grow into sociable, well-mannered adults with a healthy respect for their fellow beings. Barbara Sykes explains how to recognise and understand the causes of hostility in dogs, and how to move forward in a calm and sympathetic way in order to gain a dog’s respect and friendship. The author is an experienced dog trainer and her common-sense approach to behavioural problems in dogs is successfully proven in this book by the rehabilitation of Craig.
