Many people can only watch helplessly as their dog acts like a wild animal when he sees another dog, even from a distance. Why are some dogs aggressive on the lead? Which factors reinforce their behaviour? How does the person behave when a conflict arises? In her book, Nadin Matthews looks at the very common phenomenon of lead aggression in dogs, independently of popular training methods. She sheds light on the causes of this kind of behaviour and explains the dog's motivations and how the owner's behaviour may exacerbate the problem. It is heartening to find your own path to dealing with problems and to walk this path more successfully than you would by using others' teaching methods.
