Before You Bring Your Adopted Dog Home

Initial Considerations

Where your dog will be spending most of his time? Because he will be under a lot of stress with the change of environment (from shelter or foster home to your house), he may forget any housebreaking (if any) he’s learned. Often a kitchen will work best for easy clean-up.
Dog-proof the area where your pooch will spend most of his time during the first few months. This may mean taping loose electrical cords to baseboards; storing household chemicals on high shelves; removing plants, rugs, and breakables; installing baby gates, etc.
Training your dog will start the first moment you have him. Take time to create a vocabulary list everyone will use when giving your dog commands (these should be very simple one-or two-word directives). This will help prevent confusion and help your dog learn his commands more quickly.
Bring an ID tag with your phone number on it with you when you pick up your dog so that he has an extra measure of safety for the ride home and the first few uneasy days. If he is micro-chipped, be sure to register your contact information with the chip’s company, if the rescue or shelter did not already do so.

The First Day

Moving is stressful — and your new dog feels the same way! Give him time to acclimate to your home and family before introducing him to strangers. If you have kids, make sure they know how to approach the dog without overwhelming him.
When you pick up your dog, remember to ask what and when he was fed. Replicate that schedule for at least the first few days to avoid gastric distress. If you wish to switch to a different brand, do so over a period of about a week by adding one part new food to three parts of the old for several days; then switch to half new food, half old, and then one part old to three parts new.
On the way home, your dog should be safely secured, preferably in a crate. Some dogs find car trips stressful, so having him in a safe place will make the trip home easier on him and you.
Once home, take him to his toileting area immediately and spend a good amount of time with him so he will get used to the area and relieve himself. Even if your dog does relieve himself during this time, be prepared for accidents. Coming into a new home with new people, new smells and new sounds will throw even the most housebroken dog off-track, so be ready just in case.
From there, start your schedule of feeding, toileting and play/exercise. From the first day, your dog will need family time and brief periods of solitary confinement. Don’t give in and comfort him if he whines when left alone. Instead, give him attention for good behavior, such as chewing on a toy or resting quietly.
For the first few days, remain calm and quiet around your dog, limiting too much excitement (such as the dog park or neighborhood children). Not only will this allow your dog to settle in easier, it will give you more one-on-one time to get to know him and his likes/dislikes.

The Following Weeks

People often say they don’t see their dog’s true personality until several weeks after adoption. Your dog will be a bit uneasy at first as he gets to know you. Be patient and understanding while also keeping to the schedule you intend to maintain for feeding, walks, etc. This schedule will show your dog what is expected of him as well as what he can expect from you. Give him the love and attention he requires and you'll bond in no time!
After discussing it with your veterinarian to ensure your dog has all the necessary vaccines, you may wish to take your dog to group training classes or the dog park. Pay close attention to your dog’s body language to be sure he’s having a good time and is not fearful or a dog park bully.
If you encounter behavior issues you are unfamiliar with, ask your veterinarian for a trainer recommendation. Select a trainer who uses positive-reinforcement techniques to help you and your dog overcome these behavior obstacles.
