Dog's adaptation to a new home & master
If the puppy socialization is correct, the most probable thing is it will get into its new home without a problem because it will already know what a house is like and it will simply want to explore the new one. If this is your case, let your dog explore with no restrictions, but always keeping an eye on it. Two minutes on the phone or vacuuming would be enough to find out that your puppy has already chewed the electrical cable, has jumped out a window or has swallowed any other dangerous object while you had back to the puppy. Since nobody has eyes on the back of their heads, the best thing is to find the way to isolate the puppy so it can sleep or play with no problems in a safe place while you are busy. Dog Jackets
A SAFE SHELTER
A cage or interior kennels are ideal to isolate the puppy from any danger, but if you don't have one, you can create an area or a playpen with isolation fences placed near the kitchen's door. The puppies usually alternate periods of high activity with periods of deep sleep. To get your dog used to being alone at its cage for some time, wait until it is tired of exploring or even until the dog is asleep, taking it in your arms and carefully take it to its bed. Leave the dog sleeping in this safe shelter and take this time to for yourself before the puppy wakes up and begins to mess around once again.
SENDING THE DOG TO SLEEP
If you have managed to get your dog used to stay inside its cage during some periods of time, several times a day, then it will be a lot easier to send it to sleep. You are the only one who has to decide which will be the best place for the dog to sleep, but if you share your bed with that cute little Labrador puppy don't forget that it will get heavier tomorrow and you may regret letting it acquire this habit.
Dogs are sociable animals and it may be hard for some of them to sleep alone during the first night in the new house. In that case, they will sob and howl looking for comfort from you. If you manage to put them inside a high bordered cardboard box with a folded blanket on the bottom, you can have the dog in your room so you won't be worried thinking about the things that may be happening while you are sleeping. Puppies dislike wetting their beds and if the can't go out to urinate or defecate, they will normally make noises as a way of asking you to take them out and giving you enough time to wake up and quickly take them to the appropriate place for this purpose in order to avoid accidents.
If you don't want the puppy to sleep in your room, get it a comfortable and warm bed in the kitchen or in its nest and leave it there, but do not come back to comfort the puppy every time you hear it whining, otherwise you will be teaching your dog how to manipulate you. Only a few dogs can spend the whole night without urinating, so you will have to set an alarm clock and wake up during the night to take it out or clean everything up in the morning, but the last option will cause that your dog will take longer to learn what is the correct place for that purpose.
ADAPTATION OF THE ADULT DOG
For a readopted dog, the first hours in the new house can be traumatic. Take the dog to the garden or terrace first, encouraging it to urinate or defecate and then go inside back to the house with the dog and let it watch everything quietly, showing it one part of the house at a time, so the dog won't run around the house crazy & overexcited. If the dog didn't want to urinate at first, be aware and take it out frequently, the dog will end up feeling relaxed enough to do it.
The most common problem for the readopted or rescued dogs is that can't cope when they are left alone at home. It is important to leave them alone for short periods in a safe place with their beds and some toys during the first days. This, joined to patience and good stimulus will help the dog feel safer and safer. Fun is what the dog needs most.
