Often described as ‘man's best friend’, dogs have evolved to live closely with humans, and have become for many of us, long-term trusted and loved companions and friends. Unfortunately, however, behaviour problems do arise.

Given that the dog is a very different species to the human being, it is inevitable that misunderstandings occur. After all, we speak different languages, we value different resources, and we, humans do not even faintly resemble our canine counterparts. We do not have tails that wag when we are happy, and friendly and when we withdraw our lips from our teeth in a smile, it is perfectly reasonable for a dog to interpret such a gesture as an aggressive one!
