Entering a new environment can be overwhelming for a new dog or puppy. Meeting new people, smelling new things and experiencing a new environment can be overwhelming, so if you can plan to have the first full day at home with your new pooch, that would be best. To help them make the transition to their new space, start by creating a welcoming space before they arrive. Be sure to at least have a comfortable bed, size-appropriate crate, some toys and food and water bowls. When they come home, allow them to explore their new home under supervision, taking it one space at a time. Keep new meetings, of both people and other pets, to a minimum until they begin to gain confidence.
