Dogs thrive off routine, so from day one in your new home you should try to stick to the same meal time routines, walk times and bed times. It can be a good idea to limit how many rooms they have access to, at least in the beginning, to prevent unwanted chewing or accidents that you don’t want.
You can put up safety gates and shut doors to do this. A calming spray or plug-in can stop your dog from feeling anxious.
Dogs can benefit from having a dog crate that they can retreat to when they want time on their own, especially when in a new environment. They might regress with their toilet training, but it’s important to keep putting them out and not get annoyed. If they do spray in the house, you’ll want to clean it up straight away and remove the odour.
