The way we interact with our dogs, combined with their own predisposition, can lead to problem behaviours developing.

Most problems in dogs, such as chewing, are related to stress. Dogs who are prone to chewing may often choose objects that smell of the owner, especially if the chewing is related to a stress about the owner's absence.

If a dog is doted on, and receives 'praise on demand' all the time on the weekend, it can lead to him wanting constant social gratification. During the week, when the owner is absent at work, the dog can become frustrated that his 'emotional food' is gone. This is especially true if he is left alone for long periods of time. Boredom is another factor here.

Whilst a certain amount of stress is healthy, some dogs are more prone to a stress type reaction more than others, even if they are from the same litter.
