What happens if a dog is not crated?

Not crating a dog benefits its physical and mental health, making it more cheerful and outgoing, more trusting and clingy toward its owner. It also avoids long confinement in a small space that harms bone development through lack of exercise. But a free dog may secretly destroy furniture or relieve itself indoors.

In addition, some large or aggressive dogs should be crated appropriately to calm their temper and prevent them from attacking guests.
