Dogs enjoy routine. It gives them a sense of security knowing when they will be fed, when they will be let out to relieve themselves, and when they will go for a walk. Dogs like to know where they sleep, where they are allowed to go, and what belongs to them in terms of bedding, toys and food dishes. The sooner you establish a routine the sooner the dog will settle down and feel more relaxed. You must be aware that your routine may differ from what the dog was used to in its previous home so be patient and understanding. If you experience behaviours that you do not understand and are unsure of how to deal with, I suggest contacting a reputable dog behaviourist or trainer in your area. These trained professionals can often resolve an issue quickly and easily before it becomes a serious problem.
