Adopting a dog will bring joy into your home. Keep in mind both of you will need to make some adjustments. Adopted dogs need time to get used to unfamiliar surroundings, changes in their routine and new rules. The following tips are to help make this as stress-free as possible for both of you .
Establishing rules right away will help your pet adjust to its new life. Don’t feel tempted to give your new dog free reign of the house, especially in the first few days. This will make life together more pleasant in the long run. Rules should include where to pee and poop, which parts of your home are off limits and what types of behavior are inappropriate, Treats will help, especially with teaching what is and isn't okay in the home. Spend some time on Google to see which training method fits your situation best.
Don't forget it’s a dog not a person, new rules will take some time to understand. Negative reactions like shouting, yelling or hitting can make you new pet nervous and scared which leads to the opposite behavior you are looking for. Instead, stay calm and focus on working with your dog on following the rules. Lovingly guiding your dog through this adjustment period will help you build a bond that will last forever.
The new adjustment could take a while so make sure you supervise your new dog as much as possible. Always try and crate train in a crate that gives them enough room to move around comfortably. Some dogs will have a very hard time getting use to being in a crate (google). Try being home as often as you can after the adoption, so both of you can adjust. Using a Kong (google Kong training) will allow your dog to be distracted from the fact that they are kenneled and will give a dog something to do while they wait for you to come home.
The amount of time it takes for your dog to go through an adjustment period can vary. Some dogs get used to their new home in a week or two, while others need a few months to fully adjust.
